TSA Puts Off Safety Study of X-ray Body Scanners

zokuga writes "ProPublica reports that the TSA is backing off a previous promise to conduct a new independent study of X-ray body scanners used at airport security lanes around the country. Earlier this month, an investigation found that TSA had glossed over research about the risks from the X-rays."

What cost? Ionizing radiation is bad for you. There, no charge. When there's a benefit, then the risk may be justified, such as in medical applications, but security theater is not a good enough reason for exposing people to ionizing radiation.

Preaching to the choir, AC.

I underwent Radiation Therapy for 6 weeks after having a malignant tumor removed. My doctors, ever since, have tried to minimize how frequently I have X-Rays taken, opting for MagRes or Ultrasound to check things. I feel I've been baked and now must be wary.

"Perhaps they're backing down because of the cost - someone wants government spending to be less liberal (Ha!)"

This type of expense, could be conducted, at 0 cost to the taxpayers, if the airline customers were made to pay for it, instead of people flying from texas to orlando for $5, courtesy government subsidized transport, so that disney can post record profits.

Sucks that people who never fly, continually pay for those that do, via these subsidies.

That said, as a taxpayer, even tho I dont fly, I'm willing to pay for someone with a fancy college degree, to stick a radiation meter inside a scanner, perform a scan, use a cheap calculator to do some quick math, and type up a report. It's not rocket science and would cost all of $100 in the private sector. But of course, since the government is involved, it'll cost $10 million.

Re:And we're surprised by this?

[colinnwn]

The TSA security fees alone flying from Texas to Orlando (given a connecting flight) could be $5 alone, so I don't get the snark. You'd be hard pressed to find a ticket from TX to FL for less than $140 after taxes. The Federal Government (courtesy of the TSA) enormously overspends on aviation security based on the risk of death to any particular individual versus other common risks we experience every day.

Part of this is due to the fact aviation security threats (and operational risks like crashing) can affect people on the ground who never fly. Part is due to the way an aviation problem can make the entire US populace apoplectic for some strange reason. And part is the general authoritarian streak of our government. So I don't think it is unreasonable aviation security is partly subsidized, when most transportation related infrastructure and fuels in the US are massively subsidized as well.

Re:And we're surprised by this?

[fsckmnky]

You make a good point about the security of the people and buildings underneath the airplane. But this doesn't explain the millions if not billions spent on rural airports that service 2 flights a week so some senator can get his name on the place and his buddies can go hunting. There must be some rational, economic, middle ground.

Re:And we're surprised by this?

[fsckmnky]

Now that a think about it, no. As a homeowner, my activities did not endanger my home from airplanes. It is the activity of the airline industry that endangers people and homes. Unless you want to argue that shelter is not required to support human life, but flying is.

That said, if I order something and the package is flown via airplane, then the shipping cost should reflect it.

Re:And we're surprised by this?

Incidentally, I flew from Austin to DFW last week, and all the gates I saw were using millimeter wave scanners.

Re:And we're surprised by this?

[colinnwn]

There is no excuse for the Essential Air Service Program other than to give lawmakers and rural residents a warm and fuzzy about deregulation. It was even less useful than the poorly allocated farm subsidies to society as a whole.

Re:And we're surprised by this?

[fsckmnky]

I don't at all disagree with you, however, I just wanted to point out, that the farm subsidies, originally, were intended to solve a problem of malnutrition, because at the time they were implemented, people in the US were in fact undernourished. Sadly, it has since been co-opted by politicians buying votes from the agricultural industry and is as bloated now as the general population is.

Rational economic actors would reduce the subsidies, as the general population became more and more obese, but, as you and I both are aware, the actors are not at all rational.

Re:And we're surprised by this?

[colinnwn]

No, but as a homeowner, or just as a living person, there are many risks you have no option in whether you participate in, or if you try to reduce, you are probably increasing your risk exposure elsewhere. Homeowners insurance protects you for some of those risks. From a realistic perspective, the aviation industry, just like the automobile lifestyle in the USA, isn't optional.

Air carriers carried insurance for damage to people and property on the ground related to accidents at reasonable rate pre 9/11. A large damage event related to terrorism was considered so unlikely, that component was very cheap. Now it is so expensive, based on one large scale event, it is subsidized by the government. Aviation security also is so expensive and overwrought by the government, that it is a similar type of extremely expensive insurance (to the tune of +$6 billion per year). That package flown by airplane for $15, would probably be about $50 if the Fed Gov didn't subsidize any form of aviation expense.

People aren't required to carry insurance to protect others in case their car is carjacked and driven into a restaurant full of people. Gun makers generally don't have to pay claims to victims when a criminal or terrorist uses their product illegally. I don't see any reason aviation should work differently as far as security goes. And I also think the only 2 things that have made us safer since 9-11 are passengers know to fight back, and reinforced cockpit doors. TSA is 90% waste of passengers and taxpayer's money. Though I do greatly miss how pilots would sometimes leave the cockpit door open and you could see up there as they worked.

Re:And we're surprised by this?

[colinnwn]

That's why I said it was less useful. The farm subsidies were good for a little while, but poorly implemented to allow the process to be extremely political as our diet preferences and nutrition science advanced. EAS really just transferred wealth from urban to rural residents. It would have been cheaper and more efficient (though I believe equally unnecessary) to allow rural residents to deduct part of their airplane tickets from their taxes, to reimburse them for the longer and more expensive car trip into cities to catch flights.

Re:And we're surprised by this?

[fsckmnky]

Business expenses are already deductible, unless of course, that expense is in the form of a tax, levied upon people, to support the business of another, at which point the person incurring the expense is screwed. This is why the "real cost" is important.

Re:And we're surprised by this?

[colinnwn]

You have a point that rural commercial aviation business travel is being both subsidized and deducted. That may not be in the national interest. Though I was more thinking about personal travel.

I'm not entirely against all subsidies. There can be externalites that make subsidizing an activity valuable to society as a whole. For example we wouldn't want everyone to move to the cities because life was better and cheaper here, and have no one living in rural communites to help farm and ranch. But we also don't want to subsidize people to live in rural areas just because they want to have a nice big spread of land, but they aren't using it to productive effect, and drive into the cities for a "better" job.

Obvioulsy the situation we have with subsidies now is out of control and terribly inefficient, while in many cases providing little or negative societal value.

Re:And we're surprised by this?

[Obfuscant]

But this doesn't explain the millions if not billions spent on rural airports that service 2 flights a week

Billions? Millions maybe, if the entire runway is replaced, but billions?

You forget that those smaller airports also serve the communities in other ways than just flying a senator's buddies in to go hunting. Businesses make use of them for transport, air cargo, training of future pilots, search and rescue operations, etc.

There aren't many small airports that service only two flights a week. Certainly not any that have gotten millions of dollars in federal money.

Re:And we're surprised by this?

[fsckmnky]

My point isnt that the airports aren't useful in any way, my point is that if they are useful to the community, then the community should pay for it. If it is too expensive for the community to pay for, then economically speaking, that should be a red flag that it isn't really useful, as it is not producing enough return to support itself.

Have you heard of the "Runway for no one"? http://news.blogs.cnn.com/2011/09/28/a-64-million-runway-for-no-one-in-alaska/

Re:And we're surprised by this?

[fsckmnky]

I feel the need to clarify my use of the word "community" here. I mean, "all who benefit from". A brief example, before I move on.

Suppose there is oil in Alaska, within 50 miles of a small village inhabited by Alaskan natives. Arguably, the existence of the village, is necessary, for the oil industry to gain access to the oil. It's somewhat of a chicken and egg problem. "There's lots of oil in the ground, but we can't get it, because there is no support infrastructure nearby."

Certainly an investment in the infrastructure, would allow for the extraction of the oil. We all benefit from the supply of oil ( although some posters, using a computer, made entirely thanks to oil, would pretend they dont use oil ). This is where the slippery slope starts.

The oil industry says "hey uncle same, give $20,000,000 to the village to build infrastructure so we can get that oil cheap enough to utilize it." Uncle Sam says "yeah, we need more oil, okay, here is your check." The oil company gets the oil at $3.00 a gallon, and sells it for $4.00 making a profit of $1 ( very simplified assumption). Without the $20 million subsidy, the oil would have cost $4.50 a gallon to obtain, at a loss of $0.50 a gallon, making it not possible for the oil company to extract it.

Ding ding ding ding ding. The oil industry should be looking for low hanging fruit. You can't get it at a profit, fine, go look for oil somewhere else that is profitable, and when the price of oil rises eventually due to scarcity, the project will pay for itself.

If instead you tax everyone, to get the oil, that is too expensive to get, you make it harder for grandma to buy groceries unnecessarily, because she is paying extra taxes to support an effort that isn't profitable ( efficient ) given the current environment. It is almost the equivalent of passing a law, that requires grandma, to drive at least 100 miles to buy groceries, when there is a store right down the street.

Im sure theres details I got wrong here, but it's meant to be a simple assumption. Reality is far more complex.

Re:And we're surprised by this?

Exactly!

Face it: The scanners don't work and neither does the grope search. By working mean "detecting hidden weapons" of course. Neither does the carry-on rules about liquids by the way. It takes less than 200 ml of liquid explosive to blow a fatal hole in a plane, but you're allowed five times that. Add to that that nothing prevents you from combining your stuff if you're more than a lone terrorist. If you're part of a cell and board with a 'staff' of five (like the 9/11 terrorists did), you have a lot to work with.

The only way to stop terrorists is to prevent them from becoming terrorists in the first place, or at least prevent them from obtaining weapons, or just from buying a ticket or entering the airport. If you count on an ever-increasing pile of technological junk to catch them at the last possible moment, you're doing it wrong... very wrong.

In my pants pockets I have brought through my large pocket knife on a few occasions (it is a 4 inch lock blade) as well as my small pocket knife (3 blades the largest is 2.5 inches). In my coat pockets I have brought through a large handful of shotgun shells (about a dozen 3 inch 12 gauge magnum goose loads) and almost 20 rifle bullets (203 grain 7.62x54r with steel cases). It is not like I intentionally brought these through as I always have one of my pocket knives with me and have to actually think about removing it.

Re:meanwhile, Europe bans the farking things.

Actually that's almost certainly true. The number they are actually likely to catch is reduced by the prior's rarity. That's one of the bases of Bruce Schneier's claim of TSA security theater: mathematically the true positive are overwhelmed by the false positives. And using these scanners is central to endangering citizen positives with the real risk: cancer.

I'm not particularly fond of them, but I wouldn't wish cancer on anyone. And these scanners are probably increasing their chances significantly.

Unfortunately, that's exactly what it would take. The machines likely do spill some radiation, but it's going to rather low. Not Madame-Curie-glows-in-the-Dark levels. This takes years of following people and is very, very difficult to do well. From what I've seen of TSA front line troops, it's not exactly a career move so people will be moving in and out of exposures and therefore risks, people move between airports and therefore scanners making it even harder. People move and don't follow up on emails and letters and get lost to follow up. People get run over by horses.

This would be a difficult study for even the best of intentioned researchers. Count on government inefficiency and general bungling to really make it useless.

For what it's worth, someone is still studying the truck drivers that go through ports at least, and those seem to be the hardest hit by back-scatter X-ray scanners. Some truckers can get their entire cargo and truck scanned (themselves included) up to ten times a day.

And those scanners seem to be lot more powerful than the ones at the airport because they don't just see through clothes, they see through steel and cargo containers. Also many truckers are independent, this means many have to pay for their own health insurance (or go without).

If people think government agencies don't know how to talk, they should consider how much harder it will be with dozens of contractors who have different goals and often competition for each others contracts. No better way to make government look ineffective than by knowingly driving inefficiencies up and then turning around and claiming to fight against a broken-system that was carefully constructed to fail. Looks good as bulletpoint on a corporate (I mean people) funded campaign mailer or TV ad, and sounds like patriotic support of the freemarket-as if that concept is anything but a fantasy which makes Communism sound practical and efficient. Funny enough despite the deliberate manipulation by politicians who's reputations on shifting more power to undemocratic corporate behemoths, I still find myself impressed with how well the system has managed to still be debatably competitive with the private sector. I can assure you if CEOs and top management spent as much time undermining their companies success as half our elected representatives do it wouldn't even be a contest.

That said, we have plenty of normal police plus the FBI to handle that sort of thing.

And THAT said, the Department of Homeland Security is nothing more than a coordination office between the diverse rival agencies that normally handle this sort of thing, but hate each other's guts enough that they wouldn't piss on an agent from another bureau if he were on fire....

We opposition have always been here, just like the anti-Iraq war people, and I'm talking the non-hippie "war is evil types"- the pragmatists who think war is the last option but aren't silly enough to believe it shouldn't be on the table. We were there, most people disagreed based on arguably flimsy evidence or rational . What irks me though is when people revise history to suggest that we simply couldn't have made any other choice at the time. I'm not saying you are like this, I really have no clue. But for many of us Iraq in particular was obvious bullshit from the first rumblings, through the laughably unconvincing Colon Powell speech.Human memory isn't perfect and perception shapes interpretation, but its been only about 10 years, and pretending that there was never any doubt or debate is part of the reason we seem to make the same mistakes again and again. Learning, examining, and refining our opinions based on reality, not our ego is a the only long term means of success when we examine any of or individual or societal mistakes.Constructing an entire fantasy world just to make ourselves look good might feel warm and fuzzy in the short term, but future problems don't care why you were right or wrong last time. Instead they demonstrate you learned and improved on the thought processes that failed you. If people want to feel infallible get a dog, don't treat the rest of us like we are dumber than one. Admitting a mistake, especially one made based on flawed data and overly trusting and uncritical thought on a topic isn't a sin or a sign of weakness. It is quite the opposite in fact. Pretending we can do no wrong is best way one can almost guarantee another failure in the future. It used to be we waited until people died until we revised history to sanitize our errors, now it seems many of us throw reason out the window for hollow victory of never being wrong with increasing rapidness.

Shocking

If airport personnel starts wearing radiation exposure badges the number of travelers will drop down to 1% (if not 0.1%) of what it was before.

TSA wants to banish the thought that anything dangerous might be occurring in those booths. Because of that no outward signs of such danger will be ever allowed. TSA drones will be gladly sacrificed.

Because terrorists are more shocking than cancers. Just like gun control propaganda focuses on danger to children, when in reality swimming pools are responsible for more deaths.

That's a very disingenuous claim by the gun lobby. WHO is focussing on Children? YOU are.

In fact accidental drowning is responsible for about 1 death per 100,000 people in the US. Not just swimming pools, but all forms of drowning.

Whereas firearms are responsible for about 15 per 100,000.

The only way you can make the stat work to make swimming pools look more dangerous than guns is by ignoring all deaths but children's deaths. And then blaming the other side for the fact that you did it.

Here's a couple of suggestions: Don't have a swimming pool if you have young children. Don't have a gun if you're a human being.

I've heard people say, it's worth if if it saves one child. It is an argument that is used and focused on. Even outside of political arguments, most parents are more afraid of their kids being shot than drowning because the former is more shocking. Children are both much more likely to drown and much less likely to be fatally shot that the general population. Comparisons however are not disingenuous because if the arguments are made about children, so the relevant statistics are those specifically about children. Sure I didn't explicitly qualify the last, but I don't think the context was unclear.

Don't have a gun if you're a human being.

I would have fewer objections if you were willing to start with the police and army. If you object that sometimes firearms are sometimes appropriate tools after all, consider the following. The vast majority of gun violence is committed by a small minority that has a history of violence, and they aren't likely to become decent folk if deprived of a firearm. About half the victims are themselves engaged in some sort of criminal activity. Why should the majority give up their most effective defense against that minority?

Re:Give me the security I traded my privacy for

[WorBlux]

That's a highly disputed number. 254 justified homicides not by police in 2008 and I would guess mainly with firearms. [FBI] 266 injuries or deaths from lightning strikes in 2010 [struckbylightning.org]. The assumption with that is you actually need to kill someone to deter them from committing an attack is suspect. Often merely brandishing a firearm is enough to convice a criminal to leave you alone.

Again from the perspective of England, it doesn't look like your ownership of firearms has helped you one bit. Quite the contrary in fact. It looks rather like a mental patient who thinks repeatedly banging his head against a wall is going to make him feel better.

Oh dear, firearm ownership is not the only thing that affects crime. It is only a single factor which deters it and obviously not a panacea. Look up Homicide statistics per state. It carries from over 20 per capita in D.C, to less than one in New Hampshire. Demographics and social attitudes towards violence have a larger effect.

Re:Give me the security I traded my privacy for

[BasilBrush]

Of course there are many factors that vary the rate. You should take a good, long, hard look at yourselves. The richest country in the world, yet other than a few banana republics, the one with the highest per cap gun deaths.

From inside the US, it's probably difficult to see why your country is different in that way. From the outside, where we haven't had your culture trained into us from birth, it's very easy to see. The two, huge, glaring reasons are:
1) You have huge social inequality.
2) You have a unique gun culture. There are other civilised countries where gun ownership is wide, but the guns are considered tools for hunting, sport or as national defense as part of an official militia. Only in America are they held for the notion of household and personal defense, with people shouting about their pride to do that.

Well I say only in America. There are other countries where it's done. e.g. Afghanistan, Iraq, Libya, Somalia. I was talking about civilised countries.

Interesting isn't it that I should mention an official militia. That is the reason the founding fathers put gun ownership as a right. Now in places like Switzerland they do that properly - young men serve in the army for a few months, and get their basic training. And then they keep their assigned weapon. Locked away in case of war. A duty rather than a right.

Re:Give me the security I traded my privacy for

[Bob the Super Hamste]

Don't have a gun if you're a human being.

You really believe this. I grew up around firearms, learned how to handle them safely (started shooting when I was 8 using my grandfathers 12 gauge) and own a few myself. I don't believe in accidental shootings in >99.9% of cases it really is negligence. There are some that are truly accidental but those are exceedingly rare, as in you are hunting pheasants going through a field with grass up to your waist with the safety on and step into a gopher hole fall on your gun and set it off. My 3 firearms (2 rifles and a shotgun) are safely stored in one of those nice fireproof gun safes that you blot into floor. Do I ever worry about my firearms shooting another person. Hell no. I practice safe storage, handling, and transporting. They are only loaded when I plan on using them (hunting, or target shooting) and are only pointed at things I intend to shoot (targets or tasty animals) I am also aware of what is around me and what I am shooting at since most rifle bullets will go through the target and continue on their path so you need to know what is behind what you are shooting. I don't shoot at noise, I identify my target before pointing my firearm at it. My chain saw, ax, crosscut saw, or splitting maul are more likely to cause harm to someone than my firearms. Too many people view firearms as an extension of their cock instead of a tool. Personally I think that people who commit crimes with guns should have the book thrown at them as responsible owners get a bad rap.

Re:Give me the security I traded my privacy for

[Bob the Super Hamste]

Here in the US there are different attitudes towards firearms. There are those that view it as an extension of their cock which they can wave around and show just how tough they are. There are those who fear them and seem to believe that they will magically grow legs and walk up and shoot you (some of my wife's relatives think like this). There are those who show the proper respect and use them as tools. Finally there are those who view firearms as basically a toy and are reckless with them. The problem groups are the ones who think it is an extension of their cock or that it is a toy. I would say a majority of gun owners fall in to the category of showing proper respect and that it is tool but you never hear about those people as they never make the news unless one of them bags a massive buck and makes the back page of the sports section in the new paper. So the people in the category who fear guns only hear about the idiots that cause problems and thus are terrified of firearms.

Currently there has been a lot of glamorization of guns within the hip hop culture thus only encouraging those who view a firearm as something to show how tough they are. Contrast that with some rural areas where hunting is a way of life almost everyone owns a rifle and or a shotgun. They don't have the gun crime that you seen in the inner cities as people there view them as a tool.

By not having a gun, I'm not reducing my chances of being shot, I'm reducing my chances of being able to shoot back (read: defend myself) if I'm ever being shot at.

Taking guns out of the hands of law-abiding citizens will keep them out of the hands of those who would use them to break the law about as well as taking marijuana out of the hands of law-abiding citizens has kept if out of the hands of those who smoke it. The difference here is, while marijuana may or may not (I lean towards not) be harmful to the person using it (and only to them), the illegal gun can be harmful to everyone around the person holding it. Knowing that, I think I'll hang on to my protection piece, thank you very much.

Re:Give me the security I traded my privacy for

[WorBlux]

Unfortunately Militia's don't work well for empires. "That is the reason" No, that is a reason, though the most important one in the context of that era. Rights and duties are inverse. I have a duty to defend myself, my family, and my neighbors, and thus have a right to acquire and carry arms to this effect.

1. That's part of it. Look also at the overbearing drug ware which further disenfranchises the poor, and victimless crime laws that create a divide between the police and citizens, and create new markets that support criminal operations. In addition these markets are more likely to be violent as there is no recourse to the courts. It also diverts resources away from dealing with violent defenders. This is in addition to regulation which make self-improvement and mutual aid difficult to practice.

2. No, guns are defense are are larger part of a culture of self-reliance. The facts just don't stack up with your assertion, as those who display thier interest in defense by applying for conceal carry permits are almost never responsible for incidents of gun violence. You know who are? People with a long history of violence or mental illness. Yes I admit the U.S could do a better job are keeping arms away from such people, but unfortanatly simple sensibility has little place in our political system.

3. Suicide by firearms makes up large portion of gun deaths in the U.S. It is tragically more effective for this than any other popular means, so fewer people survive though their attempts at such. However this again speaks of a social problem that is deeper than merely owning firearms. Even so the total rate of suicide is less that most European nations.

Why were the radiation levels not a purchasing requirement? I would expect any radiation unit to have the exposure level very clearly identified.

Either specify that all units supplied must be under a maximum exposure (at all points in their operating life) set by the TSA or the supplier is liable.
Or the supplier can specify an exposure level when delivering the unit and the TSA can decide to accept or decline the purpose.

In either case the design limit should be easily available. And publishable as a start.
If the design limit is not available, then on what criteria where the purchases authorized and who authorized the purchases without strict exposure limits.

The point is that ANY ionizing radiation increases the risk of cancer, and therefore, statistically speaking, over a large population these scanners WILL kill people, its just a matter of how many lives are we willing to sacrifice for the facade of security.

Considering that the dose from a scan is equivalent to a few minutes of flying on a geomagnetically quiet day, more people are getting killed from cancer induced by flying than by getting scanned. If you're that concerned about additional radiation, you should be checking for any unusual geomagnetic activity before flying, especially at high geomagnetic latitudes or maybe just give up flying altogether.

Infrequent flyers will often have more to worry about the radiation dose from their own homes from radon and normally occurring radioactive materials in many building materials.

Re:Choose yer poison

[hey!]

Well, the formula is different when you choose for a population than when you choose as a member of the population.

As a member of the flying public, your considerations are dominated by two very immediate things: the indignity of being scanned or the indignity of being patted down. And because you *must* submit to one or the other, these certainties are likely to be more meaningful to you than any remote improbability, like being on a plane that is hijacked or receiving a cancer-causing mutation from the scanning machine.

If you're somebody who sets policy for the flying public, what is a remote improbability for any individual becomes a near certainty you have to deal with. That is to say, it is *certain* that somebody is plotting to hijack a plane somewhere and you've got to do something about it, even though it won't affect the vast majority of people who are flying. Suppose it is ALSO nearly certain that the gazillion radiation exposures you're mandating cause a certain number of cases of cancer, including deaths. You ALSO have to deal with that, even though it's no big deal to the vast majority of fliers.

The law of large numbers doesn't let you off the hook here; in fact it puts you *on* the hook. A tiny marginal difference in cancer probabilities summed over all the radiation exposures amounts to a number of people who get sick or die *as a result of actions you have taken*.

This doesn't mean you don't take action. It means you act *responsibly*.

Suppose the expected number of people to die from terrorism is 10, but the expected number of people to die from cancer is 3; you take the cancer and 7 more people (net) get to live. It's a no-brainer. But suppose because of your sloppy work the number of people who get cancer is actually *6*. That's still better than 10, but you don't get to pat yourself on the back for saving 4 people. On the contrary, you're responsible for 3 deaths that wouldn't have happened if you'd done your job properly.

Re:Choose yer poison

[Anonymous Coward]

If only there were some way to have 0 hijacking-related death and 0 scanner-related deaths. Like, you know, some sort of practical, non-cancer causing security. But I guess that sort of thing doesn't exist anymore.

When you're setting policy you might also want to consider the relative importance of stopping hijacking versus the other things you could spend time and money on, that might be more meaningful. Even without terrorism cars kill a lot more people than airplanes; it might be well worth a couple of aviation hijackings if we could drop the automative accident fatality rate by any significant amount. Heck, simply reducing the amount of slow, unless scanning at airports might help, by encouraging people to fly instead of drive.

Re:Choose yer poison

[evil_aaronm]

That's kind of my point: they're using extremes to justify the additional radiation and groping - if we don't do this, people will die!!! - while ignoring our concerns about increased risk of cancer and the trampling of our poor rights. In other words, double-standards.

Really: what's the probability that, if I got my pocket knife past security, I could take the plane down? For this thought experiment, assume that I am -not- Chuck Norris.

See, this is actually a perfectly reasonable way to assess risk mitigation options.

Unfortunately, we don't know what the expected numbers of people to die from terrorism is, and we also don't know what the expected number of people to die from cancer is -- partially because the people in charge don't want to let anyone figure out how much radiation these things leak. And on top of that, the expected number of people to die from terrorism is likely a rounding error above 0 past 5 or 6 digits after the decimal point. You don't devise policy around one-in-a-million scenarios.

And how effective are these things anyway? Will it detect plastic or ceramic knives? Can things be hidden by wrapping them in a stealth case (stealth plane technology)? A lot of the captured terrorists were science/engineering students, so they should be somewhat imaginative.

Re:Choose yer poison

[sjames]

On the other hand, what if the cancer deaths is 15? Then you just killed 5 extra people.

Of course, given the TSAs intense resistance to even look into it means they don't actually care if you live or die at all, so long as they get more power. If they were actually on the side of good, they would be extremely interested in how many cancer deaths they might cause in the name of preventing terrorism deaths.

Of course, as a member of the population, my choice would be no scanner and no pat down.

Re:Choose yer poison

[hey!]

The main point I was making was that the (debatable) idea that the scanners serve some important public purpose does not excuse the government from any harm they do.

A secondary point is that you *do* have to take one in a million events into account when you are managing millions of trials that might produce that event; you just have to weigh it accordingly.

I think we would still need expensive training as the current agents doing the screening seem to miss simple things with those technologies like shotgun shells, rifle bullets, and pocket knives, all of which are easily detectable by a metal detector, or carry-on x-ray scanner.

I've only been asked to go through one of those machines once, at the New Orleans airport. Every other airport I've been at (which isnt many) it seems optional. They weren't sending everything through them either. There were two lines -- one for metal detector and one for the machine, and a TSA agent alternated people between the two lines randomly. I opted out -- but didn't see anyone opt out either. The TSA agent was nice enough, but he didn't buy me dinner afterwards :(

The science experiment is on the passengers

[Anonymous Coward]

And the theoretical safe levels would only apply if these machines are set up properly. There have been cases where xray machines have been mis-calibrated and put out much higher levels than were safe. And that was in a medical facility dedicated to safety.

Of course I am sure that the TSA calibration records and maintenance records are a matter of public record on these powerful sources of radiation, and that scientists have been allowed access to these machines to confirm the governments assurances... They aren't? And they haven't?

Science is not about taking someone in powers word for the truth, it is about confirming the truth independently. It is inconceivable to me that these machines were deployed without any independent testing and with complete secrecy about dosage, calibration and maintenance records. It stinks and it stinks bad.

Only time will tell how deadly these machines are. I will bet anyone a crisp clean hundred dollar bill that these machines are at a minimum 3 orders of magnitude more harmful than the government is admitting (6,000 deaths from cancer). I am hoping they are no more harmful than 4 orders of magnitude more harmful (60,000 deaths from cancer) but fear 6+ orders of magnitude more harm (600,000 additional deaths from cancer).

But is anyone else worried that even at the levels the government admitted to that they are willing to kill 6 Americans with cancer for security theater?

They don't need to be public record. They just have to be followed like every other x ray emitting device which are regulated by the states. You want to put an x ray machine in your office? Fine, put it in then call the state radiation physicist before you light it up. They come out and check it to make sure the public is safe (you're on your own).

Guess what doesn't happen since the airports are considered federal enclaves?

Re:The science experiment is on the passengers

[TheCarp]

However... the x-ray machine in a private office is only ever aimed at customers of that office. As a customer, I could demand the calibration records, or refuse my business. Maybe they show them, maybe they don't (they probably do...and tell the story of the oddball for years)... but the point is.... these are aimed at the public. They stand in the way of using a publicly available transportation resource.

As such, I think that is a strong case for making the records public.

Re:The science experiment is on the passengers

This happens with a lot of medical equipment. A large hospital with have one machine mis-calibrated every year (my dad works as a bio medical technician repairing devices, not calibrating them) and sometimes it gets caught before it is used sometimes not. I remember one story where there was some machine for doing some heart surgery where the device was incorrectly calibrated and instead of cutting and cauterizing it vaporized a large chunk of the patient's heart.

Re:The science experiment is on the passengers

[Anonymous Coward]

I'm a medical physicist. The TSA does a nifty accounting trick in the amount of approximate dose they report. They publish that one scan is approximately 0.005 mrem of dose. However, the unit for dose is [energy deposited / mass of tissue ] and they use the mass of an average person's entire body. They report "whole body dose" when the backscattered x-rays are truly only depositing dose at the skin. The skin is approximately 16% of a person's body mass. Therefore, the skin dose of 1 scan is 0.005/0.16 = 0.03125 mrem. That is 6.25 times larger than the dose they report. Will the scans caused increased brain cancer or bodily cancers? Doubt it. Will they heighten risk for skin cancers? I certainly believe so. Fair-skinned frequent fliers ought to prepare for the pat down.

Re:The science experiment is on the passengers

[ColdWetDog]

That's fine, but the public isn't in much of position to determine if the records are good, bad or indifferent and doesn't have the power to shut down an unsafe situation. The state radiation physicist, OTOH, is empowered to keep the public safe and, presumably, knows enough of radiation physics to do so.

But enough dreaming....

well...

[rish87]

I'm not pro TSA by any means but if you look at the amount of ionizing radiation they are talking about being covered up " is extremely low, equivalent to the radiation a person would receive in a few minutes of flying" (http://www.scientificamerican.com/article.cfm?id=europe-bans-x-ray-body-scanners) I don't think quibbling over an amount of radiation literally 100's of times less than what each and every person is about to be exposed to anyway is the correct way to fight the TSA on this matter. When attacking this detail it is too easy for the government to say "so what?".

Re:well...

[Anonymous Coward]

I often see airport workers walk through the x-ray rather than going through the scanner. When I asked why they did not have to go through the scanner, I was told by a TSA employee that they go through security so many times each day that it would not be safe. But if it really is the same radiation as 2 minutes of flying, then the equivalent of a 4 hours flight would cover 100 trips through security....so, is it really that safe? Of course, my feeling is just that they know its theater and don't want to deal themself.

Re:well...

[tftp]

the amount of ionizing radiation they are talking about being covered up " is extremely low, equivalent to the radiation a person would receive in a few minutes of flying"

You gladly put yourself into a hot tub that is heated by a 2 kW electric heater. However you will not be happy if someone takes a hot soldering iron that has only 40W of power and sticks it up your body where it doesn't belong.

Or, you are happy to go to a beach and spend a few hours there. But you won't like it if someone takes a large magnifying glass and focuses the Sun's image onto your skin.

This demonstrates that talks about "total power" or "total radiation" are misleading. It is essential to understand how this power is used.

Re:well...

[Anonymous Coward]

As soon as they start regularly testing the devices, giving their staff dosimeters, putting a hardwired "emitter on" indicator in an obvious place on the device, and taking the other basic precautions necessary in every other industries that produces ionizing radiation I might be willing to consider the amount of radiation emitted by these devices to be safe. Until then the amount is a very important question -- for all we know these things are all half-broken, with a collimator that gets stuck mid-sweep, power regulator that's set to 11, and an emitter that doesn't turn off between imaging cycles. That kind of exposure could easily be 100s of times higher than safe exposure limits, and the manufacturer's claims to the contrary are not good evidence to the contrary.

Re:well...

[calidoscope]

This demonstrates that talks about "total power" or "total radiation" are misleading.

Really poor analogies. What you are referring to is energy concentrated in a small part of the body as opposed to the whole body. The scanners distribute the energy over the whole body and any breakdown with the scanning mechanism will be immediately evident in the image. Also remember when dealing with total doses on the milli-rem level, it doesn't make much of difference whether the dose occurred during a microsecond or over a day. Starting around 25 rem or so, there is a substantial difference in getting the dose in much less than a day as opposed to a couple of years.

Re:well...

[tftp]

What you are referring to is energy concentrated in a small part of the body as opposed to the whole body. The scanners distribute the energy over the whole body

That's not what I read. Most of the energy of the scanner is absorbed by the skin, and the analogy is very much correct. I'm not copying the entire content of that URL here, please go there and have a look - the letter with concerns is written not by a couple of nerds in a basement but by scientists (unless membership in the National Academy of Sciences means nothing.) Let me just cite one small paragraph:

"Unlike other scanners, these new devices operate at relatively low beam energies (28keV). The majority of their energy is delivered to the skin and the underlying tissue. Thus, while the dose would be safe if it were distributed throughout the volume of the entire body, the dose to the skin may be dangerously high."

any breakdown with the scanning mechanism will be immediately evident in the image.

That would be of little consolation to you. Let's imagine a real world scenario: the scanning stops - because, for example, someone shoved a blob of chewing gum into the gears. The machine starts working slower, slower and finally stops, with the X-ray beam focused on something totally unimportant, like your eyes or your brain (upper or lower :-) Let's say the interlocks failed and the beam is not shut off.

What would you expect from a team of inept users of this technology? Do you believe they have a clue how the machine works? Do you think they care to know? Maybe there is one geek in the whole TSA, and he is not operating the machines anyway.

The operator sees that the image is bad or incomplete. What do you think will happen? The operator WILL REPEAT THE SCAN - again and again and again, potentially burning raster tattoos into your skin with the X-ray beam. Only after several attempts he will give up. You will not be told what happened. You will be told to go to another machine or you will be molested by hand. You will not know what just occurred, and the TSA will get rid of you as fast as they can (or not, even if they themselves have no idea what they just did to you.) In any case, you will be getting radiation burns on your body within days, and good luck matching this to any specific machine in any specific airport. TSA will tell you that "safety of passengers is #1 concern of TSA and nothing like what happened to you could possibly happen to anyone, you included."

Re:well...

[blueg3]

Both flying and Compton backscatter scanners are well, well below acute exposure rates. The only concern is ionization causing DNA damage (which could lead to cancer). That effect is linear in total exposure. So, just looking at total exposure is, in this case, correct.

Re:Where can I buy a Dosimeter?

[TheCarp]

Honestly... I think someone needs to talk to some hospital workers. Any hospital could easily help with this, and could probably be convinced to do it for cost just for the fact that this really is a public service to test. Even if not, there are a lot of people in healthcare who need to wear them, so theres many options there.

My mother wore a dosimeter for years. She was an x-ray tech and was told on her first day of training "By choosing this job, you are taking 10 years off your life". Thats probably less true now. Hers was just a piece of film in a plastic case. Every once in a while they get collected and developed. Cumulative dose over time is measured and sometimes resulted in some extra mandatory vacation. um... w00t? :/

Sure its simple, you can make one, or buy them, but, having them processed by someone who is competent to do it, and can stand by their results is key for something like this. If someone at the local Hospital radiology department wanted to help, they could put this issue to rest... without much problem. Anybody can claim numbers on a device, anybody can say they developed their own film and calculated the dose.... but people who do it every day can give you results that are harder to ignore.

Re:Where can I buy a Dosimeter?

[cbope]

Problem is, that's a very unscientific way to measure the radiation dose and very inaccurate.

The main problem with determining dose to the body from ionizing radiation is that different tissues and organs of the body absorb radiation in different ways. Additionally, some tissues and organs are more sensitive to cellular damage that could potentially lead to cancer more than others. And finally, the absorption is also heavily dependent on the energy levels and spectra of the radiation itself. Some types of radiation are basically harmless and pass through the body without being absorbed. Other types are heavily absorbed and can lead to health impacts.

Accurate does measurement is challenging and even among experts in the field there are differing opinions how to weight the different measurements and come up with an accurate dose representation that translates into meaningful risk assessment.

As an engineer working in the medical imaging field over 20 years, I'm well versed in radiation safety and the effects of radiation on biological processes. These backscatter machines should have NEVER been put into public use. There is literally zero scientific evidence on their efficacy for intended use and safety for both the operator and subject being scanned. In medical imaging, the doctor makes an assessment of risk vs. benefit when deciding to take an X-ray on the patient. If the benefits outweigh the risks, then the X-ray is justified. The major problem with these scanners is that the risk is unknown due to lack of studies validating the safety of the scanners and the population is being unnecessarily exposed to ionizing radiation without a medical reason to do so. This is purely security theater at its finest. I would never voluntarily submit to being scanned by one of these machines, especially with my background knowledge in radiation. If the US government were to decide that use of these scanners is mandatory, then I would cease all travel to/from/within the US by air. As an American living abroad, the end result is alienation by my own government. I for one am glad that the EU will not allow their use, so I may safely travel by air throughout Europe and the rest of the world.

(1) An excuse I heard for why radiation badges by employees aren't be used is that they would have to be issued individually to each TSA employee (can't share)... which is expensive and also that it is prone to misuse (i.e. someone sticking in their badge in one of the machines for a few days and then giving to their superior... all hell would break loose)

(2) Millimeter-wave versions are non-ionizing (L3 tech) is now to be used as the standard across the US (so phase-out back-scatter tech which is ionizing). If this is the case- might be a mute point to perform as multi-year study now...

Re:What I heard recently

Killing millions is USA citizens at air terminals is an acceptable crime .. ergo not crime .,. that the Whie House and DoJ as well as DoS are egger to commit.

So. Fare thee well USA travellers. Wear lead linded clothing but of course the TSA will demand to squezze your balls and otherwise stick a finger up your vigana as such.

Lovely.

Erm... not true

... travelling through Chicago, I found a whole stream of people opting out (just like me). Or perhaps the TSA-person shouting "male/female assistant" was just doing that for fun every 3 minutes. And I have been through both experiences in Europe and the US: in Europe you don't even get the sign to indicate the option to "opt-out". People requesting a pat-down are much rarer there, if at all.
Although I would agree the technology is different, I think there is a bit more information on the whole process in the US, and on your rights therein.

But this is stimulating the economy, you fools, see how many jobs are created or saved by this wonderful contract. And for gawd's sake, THINK OF THE CHILLREN!

how many lives are we willing to sacrifice

Forgive me, but I just fell off my chair laughing when I read the word "we".

Please don't tell me you still believe in the fairytale of "government by the people".

MOD PARENT UP

Obvious statistical screwup is obvious - and constantly repeated by people with an irrational fear of weaponry.

Indemnity first

[flibbidyfloo]

Maybe they are putting it off until Congress can pass a law indemnifying the TSA against the lawsuits that will crop up as soon as they reveal that they knew cancer was a risk but deployed them anyway.

Afraid the truth will out of dangers.

[lsatenstein]

The reason for not doing the study is the fear that the xray machines are probably emitting dangerous levels of radiation.

They must know this from the film badges that some operators wear to show the amount of exposure to potentially death causing radiation.

Potential, yes, because the radiation can cause cancer. and cancer can cause death.

This is what happens in general

[Anonymous Coward]

If you give the government power, it will be abused against you.

Let the government set up any social or political institution, it will be constructed to enslave you. Education, social safety net, protection from criminals, protection from outside forces, protection from terrorists, protection from banks, protection from bad drugs, ...

All ruling classes are authoritarian. The more opposition they receive, the harder they tighten the screws.

The trajectory of freedom in the US is steeply downward. In the last 2 administrations we have embraced torture and extra-judicial imprisonment and killing of US citizens. We are now beginning to treat protesters as terrorists.

At the same time, most cities have installed a lot of video devices and automatic surveillance systems are watching citizens everywhere, the NSA reads all of our emails and listens to all of our phone calls. We have both a police state and a national surveillance state.

There is very likely a gulag in our future, but nobody seems at all concerned.

TSA's cancer is a minor danger compared to

[Anonymous Coward]

Yes, TSA is killing people through bureaucratic inertia combined with someone getting their pockets filled with our tax dollars. We may lose a few 10s of 1000s of citizens if this goes on forever.

TSA's development as our very own Gestapo is far more dangerous.

For that matter, the FDA kills people by the 100s of 1000s every year in the US, and 10s of Ms around the world with its bureaucratic inertia combined with the money from Big Pharma that flows into the political system and cushions the retirements of so many FDA bureaucrats. Most people now die of one of :

'yes, research has found many drugs to treat your very frequent disease, and the 4 big pharma companies are all taking one through the FDA's process, but it will be another 10 years before any of them reach market, hope you can wait',

'yes, research has found many drugs to treat your very infrequent disease, but no drug will ever reach market because nobody can make a profit after the $100 - 500M cost of getting through the regulatory barriers, too bad for you',

'yes, there are many natural substances that have a good effect on your cancer, and there are science-based reasons to believe that combinations of those substances would be very effective, but natural substances can't be patented, therefore no profits for drug companies, therefore those natural substances will never be available to MDs to treat your disease, too bad for you',

'yes, that drug is available but $10K per dose because of the huge development costs and few patients, too bad you can't afford it'.

Most news these days, around the world, is some variant of the standard 'money buys a government institution intended to protect the people, that institution now abuses the people it was intended to protect'.

Money buys power, a dynamic that is easy to grasp and the general consequences of which are easy to understand, blindingly obvious everywhere. Yet we keep hearing about the need for new laws, new regulations, the latest proposal for reform.

Progressives of both the Left and the Right have a lot to answer for.

The employees...

[Anonymous Coward]

What about the poor TSA agents who have to stand next to these machines day in and day out without any protection from the XRays too?

Re:The employees...

[Anonymous Coward]

They end up sterile, and will thus not breed.

You could argue that's actually a fine, positive example of Darwinian selection..

What annoys me is that the TSA wastes gazillions which could be used to protect properly. But hey, it wouldn't make so much money for campaign sponsors..

No One -- No. One. -- Says these things are safe

[jeko]

There is not one -- NOT ONE -- professional who has been willing to certify these devices as safe. Not one.

Rapiscan categorically denies the machines are safe. What they do say is that "These machines have been built to TSA/DHS specifications. We are not responsible for those specifications, nor are we responsible for their use."

The FDA has been denied a chance to test them as they are not "medical equipment."

TSA Head John Pistole, when directly asked by Congress about safety, covers his butt and weasel words the question with "They are as safe as we can make them... I have been told they would be safe... I believe they should be made to be safe as possible, but I am not a doctor... Technical details should be referred to technical staff, except that the details are classified because 'Terrorists/9/11.'"

He categorically refuses to say, "These machines are safe and will not cause cancer." He suggests it, he implies it, he lets reporters say it, but he never actually says it himself. His testimony bears the hallmarks of someone who has rehearsed long and hard with their lawyer.

No one -- nobody -- with an M.D. or PhD. after their name has been willing to sign off on these machines.

On the other hand, the list of serious "heavy-hitter" experts on radiation willing to shout that these machines are dangerous would fill the rest of this page.

On paper, per the published specs, the American Radiological Association has gone on record that the machines are a public health hazard. The head of Radiology at Johns Hopkins has written an open letter to the president calling the machines a danger to public health. You could fill a undergraduate auditorium with the number of professors who know what they're talking about who refuse to walk through these scanners.

Next time you hear someone from the TSA talk about how safe the scanners are, ask yourself, "If we replaced the word 'scanner' with the words 'arsenic,' 'asbestos,' or 'uranium,' would this statement still be true in the narrowest legal sense? Would the statement they just made let you hold them responsible in a court of law later? Ask yourself, "How many qualifiers did they put in this statement to sound like they just said 'The machines are safe,' without actually saying 'The machines are safe?'"

Then ask yourself how long it took the lawyers to come up with the phrasing that would let them do that.

We've seen this movie before.

[jeko]

Asbestos. Thalidomide. Agent Orange. Every EPA Superfund site ever.

The government initially comes out and says it's totally safe and effective. It takes years, but eventually the bodies stack up until it's undeniable.

They deny it anyway. The case drags on until the principals die in choking agony. Their heirs continue with the case.

Eventually, the grandkids get a tepid non-apology while the government declares "It time to move on, to look forward and not back. We all need to work together on this..."

What makes you think we'll treat the fry-machine-refugees at the TSA any better? Indeed, if you needed to find a group of hopeless chumps to irradiate for minimum wage, what better population would you find?
