TSA (Finally) Studying Health Effects of Body Scanners

An anonymous reader writes "A 2011 ProPublica series found that the TSA had glossed over the small cancer risk posed by its X-ray body scanners at airports across the country. While countries in Europe have long prohibited the scanners, the TSA is just now getting around to studying the health effects." I'm not worried; the posters and recorded announcements at the airport say these scanners raise no health concerns.

This is a distraction from the real issue.

[InvisibleClergy]

The real issue with these was never the health effects. That was just an extra thing that privacy advocates tossed in there to lend additional weight to their arguments. The primary argument against these things is the fact that they are a violation of privacy. Arguing the health issue just weakens objections, when it gets defeated.

The cancer risk is hypothetical, and if it exists it is almost certainly minute.

Re:This is a distraction from the real issue.

[Microlith]

It's more than that. It's a blatant violation of the 4th Amendment. They have no good reason to search so invasively each and every person in this country who flies. There's no basis for them to believe that every person is a possible terrorist. It's just a blatant, idiotic expansion of powers and a jobs program for the terminally unemployable so jackasses can stand behind the metal detectors and look like they're important.

The TSA has accomplished precisely shit in the entirety of its existence. It's successfully engaged in mission creep as it starts doing things for the DEA and whatnot, and managed to violate the dignity of a growing number of people. I have no respect for anyone that works for the TSA, on both a professional and personal level.

I thought cancer clusters were also discovered by TSA employees. If true, I believe that does hint there are significant health concerns and that European bans are well justified. Of course, that's all over and above the privacy violations.

Re:This is a distraction from the real issue.

[blueg3]

There are problems with many of the arguments against the scanners.
The medical danger should be a concern to everyone, but evidence suggests that the danger is negligible (though possibly nonzero).
The privacy danger is patently obvious and verifiable (though sometimes overstated), but it's just not a concern to many.
The cost-benefit argument has the problem that the "benefit" can be very difficult to accurately measure and the government may choose not to disclose data about whether the devices are beneficial. (This is, regardless, the argument I prefer.)

That's not to say there are no problems with arguments for the scanners. At the very least (the very least), it makes sense to use the microwave scanners over the X-ray backscatter. The medical danger is known to be zero, which is even better than the backscatter's best-case of "is probably zero". Even if they're less effective, we don't seem to be relying on either system to be particularly effective.

Re:This is a distraction from the real issue.

[Joce640k]

Don't you think you should care about both of those things even if one of them doesn't particularly bother YOU, personally?

Re:This is a distraction from the real issue.

[Anonymous Coward]

As others have said, I'll believe that the cancer risk is hypothetical or neglegible, but ONLY if every scanner must go through the same rigorous requirements needed for any other medical x-ray machine to be certified.

As it stands, they're built by the lowest bidder (or whoever happens to be related to someone high up in the TSA, which is possibly even worse, since they're likely corrupt as hell too). So while they're *supposed* to put out X amount of radiation, I'd like to know that it's literally an physical impossibility that it can ever put out 5X or 500X radiation due to cutting corners or poor design.

Until those are done, I'll consider the cancer risk of those to potentially be the same as the Shoe-fitting fluoroscope. Because seriously, who's telling me they're safe right now? The people that are extremely biased towards, and have the vast majority of their existence based on, the scanners being safe, after being built by the lowest common denominator.

Privacy is the only real issue with the scanners. You get a much higher radiation dose from the flight (less atmosphere to block cosmic rays) than you do from the scanners. Complaining about radiation from the scanners is kinda like complaining the cooling mister the public swimming pool has set up is getting you wet just before you jump into the pool. If you're that worried about getting cancer you'd drive instead of fly, just like if you were that worried about getting wet you wouldn't be swimming.

Re:This is a distraction from the real issue.

The medical danger should be a concern to everyone, but evidence suggests that the danger is negligible (though possibly nonzero).

But, ironically, bigger than the terrorism risk it's designed to prevent. Apart from the rest of your opinion, which I share, it also feels incredibly stupid to spend trucks of money to actually INCREASE my risk, especially given the economic circumstances and alternatives.

And I'm not even considering that how efficient the scanners are in preventing the terrorism risk in general, which I deem next to zero too. So all things considered, you spend a lot, hazzle and disrespect people considerably, step over privacy rights, don't prevent much and end up adding a new, bigger risk. Fucking brilliant!

I'm not convinced that the medical risk is bigger than the risk of terrorism it's designed to prevent. I might be convinced that it's bigger than its capacity to actually reduce that risk of terrorism. But for one, the medical risk is really, really small and for another, at that level both things are frustratingly difficult to accurately quantify.

I don't particularly think the scanners are effective at much of anything, especially if you compare them to the impact of other possible expenditures of the same amount of money (which you should). I don't know that there are any good numbers on this, or even if good numbers would be reasonable to obtain, but it is my opinion.

Re:This is a distraction from the real issue.

[aaarrrgggh]

The homicide rate in the US is about 5/100,000, so making a whole lot of sweeping assumptions, you would expect to see 9 homicides per year in airports and on airplanes past the security checkpoints. There are about 330 primary airports, so maybe 1,000 checkpoints active on average. That gives each checkpoint a 1% chance of finding a "bad guy" per year.

If on the other hand, you did absolutely no security screening, what would the mortality rate be? Let's just say there were just police officers walking around the airport. Statistically, one plane will go down every ~15 years. Add in metal detectors, and the rate likely is cut in half. Check for boarding passes and you likely drop it in half again. I don't think full body cavity searches is going to provide much in the way of marginal security improvements.

Re:This is a distraction from the real issue.

[tftp]

Also there is a problem: once the criminal manages to go through the checkpoint, one way or another, he is in the clear and has the red carpet all the way to the airplane.

If enough people have the intent, they can carry a ton of explosives into the secure area, one gram at a time. Nobody would pay any attention to their actions, and small quantities of anything cannot be detected. So in the end it's just a matter of money.

Re:This is a distraction from the real issue.

[loneDreamer]

I did find this talk some time ago: http://www.ted.com/talks/marc_goodman_a_vision_of_crimes_in_the_future.html. It's interesting in noticing that security is almost impossible as damaging is much easier than preventing damage. The problem with terrorist is that little can actually be done to stop it. As it was recently proved, a single person with a gun can shock the world. Do that 10 times in random locations and see what happens... hell, I can think of many ways to create terror myself, without trying much.

I read somewhere that one of Bin Laden's objectives was to make the US spend 1 millon for each dolar that they spent. It is guerrilla warfare, it's all they've got, and they have been extremely successful at it. The values and way of life the US people were so proud about are gone. The millions were spent and continue to be. Sadly, the root of the issue it that, bared some reasonable efforts, the only way to fight terror is by enduring it and not being scared. Luckily, very few people are actually determined to do real damage and cause pain.

Re:This is a distraction from the real issue.

[blueg3]

A reasonable and very rough estimate. I agree that scanners, and lots of other security measures, are well into poor cost-benefit territory. Of course, real measured effect is hard to come by.

That gives each checkpoint a 1% chance of finding a "bad guy" per year.

But of course the false positive rate is incredibly high, since the scanner cannot detect intent. The only way we'd get a solid estimate of how many bad guys were actually caught is if we successfully did a thorough investigation for each positive to weed out the false ones.

Making a rough estimate by the reports in the TSA's blog, the rate of people trying to bring items on airplanes that almost everyone agrees are a bad idea to have on an airplane is much higher than 1% per checkpoint-year. Yet I'd bet that their frequency of catching real bad guys is not so high.

Re:This is a distraction from the real issue.

[blueg3]

Those are some bold generalizations that are accurate enough in this context. But note that some things can be detected in smaller quantities than they can reasonably be divided into. (Plutonium can be detected in incredibly small amounts, and photons can be detected individually.) Of course in the end it's just a matter of money--with enough money they could just buy everything and blow it all up legally.

The thing is that increasing the cost of an attack is a successful defense strategy, because it reduces the frequency of an attack. Trying to plan defense so that it never fails is a fool's goal--the point is to buy enough reduction in probability or frequency of success.

The problem with terrorist is that little can actually be done to stop it.

The much, much bigger problem is that there are a small number of people who are getting very rich selling the illusion that they can do something to stop it. If it wasn't for the opportunities to funnel money into the pockets of unproductive generators of dead-weight losses in the security/industrial complex terrorism would simply be a minor nuisance, akin to traffic accidents.

I don't want to refuse to disagree with those who think you are wrong here.

However the same works in the other direction - increasing the cost of defense is a successful attack strategy. Many believe that OBL intended it to be this way. A relatively small attack, as wars go, forced the USA to spend treasure on several wars that last more than a decade to this very day. The same attack destroyed the trust within the society and paved the way for creation of a massive, centrally operated police-like apparatus that many in the US government were already itching to implement. (Note that the Patriot Act, a large piece of legislation, sprung up out of nowhere within days.) This apparatus immediately started spreading onto trains and buses and streets. TSA workers are not armed, AFAIK and so far, but they don't have to be - the police is at their beck and call at any time.

The real issue is the health effects. While I'll agree that correlation does not necessarily prove causation, it's worth noting that there was an anomalous amount of cancer going on with TSA workers at BOS, an airport that piloted these scanners. The TSA refused to even let their employees where dosimeters when this was found.

From the TSA Blog: There is a really good reason for this. The emissions from our X-ray technology are well below the requirements that would require their routine usage. To help reassure passengers and employees that the technology is safe, however, health physicists with the U.S. Army have been conducting area dosimeter surveys at multiple airports nationwide.

So, the short of it? The emissions are below the requirements that would require the routine usage of something that would detect the amount of the emissions? Wait, what? How... do ... you ... know?

I really don't give a shit if some random TSA jockey gets a look at a digital version of my junk. I'm opting out every time because I really don't want to get cancer because they refused to accept the possibility that what they're doing could be hurting people.

The homicide rate in the US is about 5/100,000, so making a whole lot of sweeping assumptions, you would expect to see 9 homicides per year in airports and on airplanes past the security checkpoints.

The problem is that your sweeping assumptions are so wrong that they completely invalidate the statistics. First and foremost, your numbers apparently assume that homicides in the U.S. are roughly random. This is, of course, not the case:

• More than half of homicides in the U.S. are drug-related, so you can start by eliminating all of those (unless we see drug deals going down on airplanes, that is).
• Approximately half of all homicides are related to domestic violence, so you can also eliminate those (because those sorts of situations tend to almost invariably happen in the home).
• The remaining single-digit percentage are mostly the result of failed robbery attempts. Nobody is going to be stupid enough do that in the presence of presumably armed security personnel, with hundreds of cameras pointing at them, in the presence of hundreds of people.

Therefore, you would expect to see approximately zero homicides every year beyond an airport checkpoint, within some small epsilon.

As long as there is a perception of chaos and disorder, people will be happy to give up every right they said they cherish. And the craziest thing is - they don't even know they are giving it up.

How is the privacy risk overstated? The government has no right to see search me. They search me, therefore I have no privacy. How is that overstated?

You perhaps see the logic error here. I say it's sometimes overstated. You state it one way and ask how that is overstating the privacy risk. Maybe it's not -- I said sometimes! I'm not a legal scholar, so I can't comment on your particular interpretation of the situation. It's a little surprising, though, if it's a violation of the 4th Amendment, that this claim is not heard more often by notable legal scholars or, say, courts.

People often insinuate that the result of the X-ray backscatter inspection is equivalent to a nude photograph of you, which is not accurate. That's overstating the privacy invasion. (I also think it's overstating the added privacy invasion to claim that such a search is particularly different from the extensive searches you already were subject to in that situation.)

There is obviously a benefit, otherwise they wouldn't do it. But it isn't the benefit we expect, or what they tell us.

You have a lot of faith in people to do smart things, apparently, followed by a rather insane government conspiracy complex.

People who have been raped DO need to "get over it". However, that doesn't justify the TSA from raping people. We should be against rape. However it all needs to be in proportion. You can't treat sex or forced sex as some taboo subject and then expect people to “get over it”. The problem is society and the media letting people of far right religious (the people who hate homosexuals, etc) to draw up all these “scary” cases (which boosts ratings). This isn't proportional and gives society the impression that people were harmed beyond repair. This isn't the case. It doesn't make rape right. But lets be honest. It is only an issue because we treat it as an issue. If you don't have an issue with sex (very few people seem to not have some issue with it) forced sex is not the end of the world. Extremely violent sex may have other physical representations with long term effect (real scars). However that is not the same thing.

Re:This is a distraction from the real issue.

Nobody with half an ounce of common sense is claiming you shouldn't care about both.

The point is that the "health risks" investigation carries the risk that scanners will be authoritatively determined to carry zero risk by an esteemed medical investigation body (chaired by the college roommate's dog's babysitter who is John Pistole's cousin, but don't let that bother you), and thus the entire case against scanners will be shot down in the press when there is still a real-but-difficult-to-quantify objection against the things on privacy grounds.

I can't answer the motivations of other individuals. In my limited experience, dentists and technicians at dentists' offices don't really know all that much about X-rays. (Yours might, I don't know.)

and why does my dentist put this heavy lead shield around me when scanning my jaw for bad teeth?

For one, I think she's legally required to. For another, those X-rays are an enormously higher dosage than the backscatter machines. (A dental X-ray is about 5 uSv. A backscatter scan is about 0.05 uSv.)

When she takes the xray, I am in a room of my own, with lead lined walls, ceiling and floor. The xray controls (button to initiate the scan) are out of range in another area.

They're actually required to be much better protected than you are, because they are subjected to occupational exposure -- they're using the X-ray machine very frequently, whereas you're only in its presence once every year or so. Unless your dental office is weird, though, the walls, ceiling, and floor are not lead-lined.

Re:This is a distraction from the real issue.

[Anonymous Coward]

As others have said, I'll believe that the cancer risk is hypothetical or neglegible, but ONLY if every scanner must go through the same rigorous requirements needed for any other medical x-ray machine to be certified.

I'd go further: both the hardware and software designs must be completely open to the public, with good design documentation being produced by the manufacturers and made available to anyone that wishes to see these documents, without charge or hassle. The government can afford to pay for companies to not consider anything about these devices a trade secret, or can choose only to do business with those companies willing to reveal these details.

Just as with open encryption standards, this approach will ultimately lead to a much higher level of both security and medical safety, as the open designs will receive far more scrutiny than any closed design could ever possibly receive. It also satisfies a fundamental human right to long term oversight over both government and businesses.

Certification alone is not enough: the technology must be open.

...In context with Fukushima and a non-polluting energy source: RADIATION BAD!

In the context of nuclear power, "radiation" really is referring to radioactive isotopes and potentially-large quantities of high-energy electromagnetic radition, alpha rays, and beta rays. In the context of a nuclear accident like Fukushima, it more is referring to the uncontrolled dispersal of radioactive isotopes (which are toxic independent of their radioactivity) and the uncontrolled release of very large quantities of mostly high-energy electromagnetic radiation.

...In context with police state enabling technology: RADIATION GOOD!

In the context of backscatter X-ray scanners, "radiation" is referring to controlled exposure to a known and very small quantity of relatively low-energy (but still ionizing) electromagnetic radiation.

As another example: In context with cell phones: RADIATION MAYBE BAD?

In the context of cell phones, "radiation" is generally referring to controlled exposure to a measurable and limited (but highly variable) quantity of low-energy, non-ionizing electromagnetic radiation.

It turns out "radiation" is used in a technical context to refer to a lot of things -- to the point that it should not be used along in a technical context. In a casual context, it's used to refer to an even broader set of things -- to the point that "radiation" does not help clarify the situation (though it may serve to incite a reaction) unless you know a priori what kind of radiation you're talking about.

Particles, not rays. Alpha (a helium nucleus) and beta (electrons/positrons) would best be described as particles. As would neutron decay, which would certainly be another serious radiation concern in a Fukushima incident.

Re:The hypocrisy just keeps getting worse.

[jmauro]

Yes and no. Only Gamma radiation is electromagnetic in nature. Alpha and Beta radiations are not photons at all, but atomic particles ejected with high energy. An Alpha particle is a helium atom without electrons and a Beta particle is free neutron.

Depending on the radiation source you may get any of the radioactive emission types and all three are dangerous, but to differing degrees depending on volume and location of exposure.

But the wavelength and penetrance is substantially different - we know an awful lot about the radiation exposure associated with flying.

We don't know what the actual risk is. Neither does TSA.

Alpha rays are a helium nucleus

Beta is electrons like what excites phosphors in yer old CRT TV.

Both Alpha and Beta are trivially shielded by small amounts of air, matter, layers of skin..etc. Normally quite harmless unless injested or inhaled then quite deadly.

Gamma rays are high energy photons like the ones presumably collected by Chekov when he beamed aboard the aircraft carrier Enterprise.

This "electromagic radiation" is quite dangerous and the reason we require large quantities of bulky matter to shield humans from exposure to "electromagnetic radiation".

So then it's just a question of what's actually necessary?

Is flight a necessary component of air travel?

Are the TSE scanners sufficiently effective to warrant their cost and possible health risks?

I'm a very frequent traveller and my main concern is with making my connections and not being fucked around for no good reason. Are these scanners actually useful? Probably not. We've seen a few demos of how these things can be tricked.

Does Heathrow security taking my photo at one desk, only so the guy at the next desk (three minutes walk away and having not cleared any other security points) can take another photo to ensure it matches? I don't see how. Why doesn't just one guy take a photo, wait a few seconds, take another and then compare the two? Even better, take one photo and compare it using the biometric passport I carry. This is unholy bullshit! How about liquids? I routinely carry whatever I want through. Last time I travelled I use the little plastic bag approach just out curiosity.

Maybe I'm an outside who can't appreciate the underlying sense in these measures. Perhaps these searches have caught terrorists in the act? I think more likely there are three things in recent years that have done way more for security:

1) Passenger awareness that the guy with the improvised weapon and hard-on for Mohammed is probably not wanting to go to Cuba

2) Locked cockpit doors

3) Removal of luggage if passengers don't board the plane.

Turns out quantifying amounts is pretty important when it comes to talking about radiation.

Incidentally, the world average exposure for radioisotopes dispersed around the globe by the Chernobyl accident (today) is about 2 microsieverts/year (uSv/yr). The radiation exposure from an X-ray backscatter scanner is 0.05 uSv/yr. So, one nuclear accident is actually exposing you to more than one X-ray backscatter scan per day.

Re:The hypocrisy just keeps getting worse.

[blueg3]

That's not really true. Mostly what we know a lot about is the damage caused by particular radioisotopes, some sources of X-rays, and nuclear accidents. The rest is modeled. X-ray backscatter scanners emit a measured amount of X-rays at a known frequency that's well within the realm of what we know about.

TSA fudged their numbers in icky misleading ways (calculating exposure as if it were spread throughout the body, etc)

Sort of. That's a common and very reasonable assumption when the dosage is many orders of magnitude below an acute dosage (which it is). Some people, after this became a big news item and political issue, disagreed. (Not that they necessarily had much opportunity to disagree beforehand.)

I'm no radiation expert, but when a group of PhD's and MD's who *are* radiation experts have concerns about the machines, then I have concerns:

http://www.npr.org/assets/news/2010/05/17/concern.pdf

The X-ray dose from these devices has often been compared in the media to the cosmic
ray exposure inherent to airplane travel or that of a chest X-ray. However, this
comparison is very misleading: both the air travel cosmic ray exposure and chest Xrays
  have much higher X-ray energies and the health consequences are appropriately
understood in terms of the whole body volume dose. In contrast, these new airport
scanners are largely depositing their energy into the skin and immediately adjacent
tissue, and since this is such a small fraction of body weight/vol, possibly by one to two
orders of magnitude, the real dose to the skin is now high.

This letter was written almost 3 years ago, have any of their concerns been addressed?

Re:The hypocrisy just keeps getting worse.

[blueg3]

I've seen this before. It's disagreed upon by experts, but I don't think these guys hold the prevailing opinion. Notably, their estimate of the difference is correct--a couple orders of magnitude. However, 2 orders of magnitude, or even 3, above what the X-ray backscatter scanners emit is still an incredibly small dose. I think this may have been written before radiation dosages for in-the-field scanners were publicly available. (Rough dosages for the prototype models have always been available, but understandably, people don't know if those figures are representative.)

Referring to them as "radiation" and calling them "alpha rays" and "beta rays" is common, semi-archaic physics terminology. Regardless, it's entirely correct when talking about radiation to call alpha and beta particles emitted as a result of a radioactive process "alpha rays" and "beta rays".

They're rays in that the particles travel in a straight line with a particular momentum. Straight line radiating from a point--that's a ray!

Also, since they're particles, they're also actually rays, in that they are waves.

Same thing as tobacco companies reporting their stuff is safe, or pretty much every pharmaceutical (coincidentally, most of them almost accidentally happen to be safe), etc etc. Even "x% of dentists prefer Y brand toothpaste".

If the machines only give one person in 100 million cancer, they're still more dangerous then the terrorism they're supposed to be preventing.

Says who? Do you have hard info on this type of radiation?

It depends on what you're actually asking. Amount of exposure caused by the devices? Body tissue absorption and cellular damage efficacy of radiation of that frequency? Dosage to cancer probability increase? All of these are publicly-documented. The most poorly-known factor, to my knowledge, is whether the linear-to-zero model of dosage to cancer probability is valid. It is, however, a fairly pessimistic model and the one that is used in estimating the danger of low-dose radiation.

Prediction

[Anonymous Coward]

In a controversial decision, the independent review decided that it didn't need to check the devices themselves, but simply re-review the findings of the TSA's own review of their own devices.

Equally controversial, the finding was that the scanners are perfectly safe, and passengers have no need to worry whatsoever. With the decision, the TSA goes ahead with its plan to eliminate the option to be patted down, forcing the only option to be to go through the scanner to fly. As well, these now become mandatory for train travel, with busses soon to follow, as well as all border crossings.

The head of the independent reviewers who brought forth the results was pleased at his results, and went back to his home which inexplicably had another floor built onto it, and a pool installed in the back yard. When asked, the reviewer claimed the funds for such an extravagant upgrade came as a gift from a friend.

Re:scanner = 13 uW cm^2; cell = 100 mW cm^2

[SecurityGuy]

Frequency matters. I can sit in front of my IR heat dish and dump watts/cm^2 into my body and get no effect other than pleasant warmth. When you start talking about ionizing radiation, that is individual photons that are energetic enough to knock electrons off atoms, you get effects that you'll never see simply by dumping energy into a volume.

I'm not bothering to look up what radiation these scanners use, merely pointing out that comparing watts is not what you want to be doing.

Some people fly ~weekly for our jobs, and that pilots and workers are subject to it multiple times a day....so, yea. We probably should do the same type of research on these that we did with cell phones. Due diligence and all that.

I'm not bothering to look up what radiation these scanners use, merely pointing out that comparing watts is not what you want to be doing.

I'm no tinfoil hatter, and there's a lot more to safety than merely peak power, and there are serious differences in primary input power vs output power aka efficiency, but there's a pretty obvious argument where if you quote the giant machine thats wired to a wall socket 30 amp 440 3-phase ckt as being 4 orders of magnitude lower power than a cellphone that runs for days off a tiny little battery, something is wrong with the numbers beyond simple comparison of wattage.

Also uW/cm figures start approaching the radio-telescope and cosmic background radiation range, like someone accidentally gave you a noise level instead of a signal level figure. Unless you cheat and use lots of attenuators, its kinda hard to make an intentional radiator at that low of a level. A couple microwatts per cm equivalent is a pretty well tempest shielded faraday cage device, for example. I used to have access to a cage like that along with an array of spectrum analyzers, standardized antennas/horns, etc. I'm sure the cheapie dell I'm in front of here emits more interference than double digit uW per cm of surface, for example.

Are you aware that X-rays are different from radio waves?

A lethal dose of X-rays (10 Gy) contains less energy than a 1-second exposure to the Sun (assuming typical human weight and surface area). The wavelength matters.

That is literally the exact form of specious reasoning that tinfoil hatters use. If you're trying to recruit them, good job. That kind of "reasoning" is very appealing to them, since it sounds logical and doesn't require a lot of thought or explanation (or even stand up to it!)

My house is wired to a 20 kW circuit. Therefore, I might as well be sitting inside 20 microwaves as be in my house. Through the power of deductive logic, since I am not burned to a crisp, I am immune to radiation.

Re:scanner = 13 uW cm^2; cell = 100 mW cm^2

Also irrelevant. Radiation exposure incidental to air travel isn't avoidable. Radiation from the scanners is completely avoidable.

And given the average TSA guy's salary, if the devices are unsafe they're getting a bigger dose from the devices annually than from flying anywhere.

Re:scanner = 13 uW cm^2; cell = 100 mW cm^2

[Grayhand]

Yeah the argument that all radiation is created equal is ridiculous. They might as well say you don't get cancer from light bulbs so the scanners are safe. I think the risk is low for some one that flies once a year but children and frequent fliers are another matter. Yes you get more radiation from the flight itself but is the extra exposure causing damage? The ugly truth is ignoring the health risks and privacy loss they haven't caught a single would be terrorist with one so they are a waste of money, period!

Re:scanner = 13 uW cm^2; cell = 100 mW cm^2

[Anonymous Coward]

A typical chest-xray and the airport scanners have the same energy and amplitude. The difference is that one is exposed for 50 milliseconds and the other (airport) is exposed for 5000 MILLISECONDS

And for the uninformed, the radiation equivalent dose is *NOT* a *LINEAR* function. The airport scanner is not simply 100x the dose, it is more like 400x the dose of the chest-xray, because it is a single-continuous exposure.

This should not be an issue

[cellocgw]

Forget whether or not there are scanners. The real issue is whether or not there should be a TSA at all. There's no evidence that the $BIGNUM dollars spent has done anything whatsoever to stop or dissuade terrorist in-flight attacks.
I'd suggest to the libertarians, Repubs, and other "personal liberty small government invisible hand of capitalism" folks that airline security should be the responsibility of the airlines themselves. I'd choose a "walk-on no problem" vendor over a "scan, remove your clothes, and provide a blood sample" vendor every time.

Re:This should not be an issue

[Anonymous Coward]

Detection systems in general have this as a common problem. It's very hard to quantify the effect that they're having on the problem they're trying to solve because the system is already in place. TSA could be deterring fifty attacks a year or none. Without a control set we really have no idea, and I don't think the public would be happy about permanently adding a few airports to a no-security list so that we can see how many terrorists take over planes from those airports. We'll never really know how effective TSA is, but the cost of terrorist attacks is so high that we'll continue funding TSA anyways.

Re:This should not be an issue

[pluther]

There are some ways of studying the effects.

For example, the FAA routinely tries to smuggle fake guns and bombs onto airplanes to see how many get through.

Last I heard, that number had not changed significantly since TSA was started.

One number that has gone up significantly since TSA took over is amount of theft from luggage and at baggage screening points. As I recall, laptop thefts went up over 1000% between 2000 - 2005.

But, major terrorist attacks - yeah, it's hard to measure changes in something that happens on the average once every twenty years.

Re:This should not be an issue

[Anonymous Coward]

Your arguments require the assumption that there is no other way to provide security than this ridiculous detection system with known flaws.

Re:This should not be an issue

[mdielmann]

There are other options. Examine countries with similar foreign policies and dissimilar airport security policies, and see which has a greater rate of captured terrorists, and which has more terrorist attempts. Of course, there just aren't a lot of countries with similar policies to the US, but there are a few countries with a similar policy by the terrorists, a prime one being Israel. So, what does Israel do to get their rates with dealing with terrorism, and why doesn't the US follow that 40-year practice instead of constantly reacting to a single threat that evaded their system?

Re:This should not be an issue

[bcong]

You're looking at it the wrong way. They don't care if you have a bomb/gun/knife in an airport, they care if you have a bomb/gun/knife and then get on a plane and it goes airborne. Then (despite the metal door) they think the plane will fly into something important.

And, fortunately for us, private airplanes could never crash into a building. Why, since they're not screened at all, the terr-ists would never think of trying to use them. Also fortuante, no terr-ists are willing to risk getting caught at a TSA booth, despite a 65% chance of getting through.

So have 3 different study organizations who are entirely unrelated to eachother or the TSA, possibly located in different countries to avoid bias (although that last part is likely not possible). Have an oversight committee watching over all steps of the review process for all three, with full transparency publishing the ongoing results of the studies as they happen to avoid any of them tossing out 'outliers' in the data at the end that should in all reality have been left in.

If all 3 find the same results, I'll believe it. Otherwise, a single group is just a single "gift" away from being worthless.

I mean shit, even mathematicians and scientists go through more rigorous independent tests to verify results for a new theorem! And guess what, it's *literally* physical impossible that a mathematical theorem can give me cancer, so why the fuck should the TSA get off easier than them?

TSA incompetence

[Anonymous Coward]

"These scanners should have to go through the same FDA approval process as any medical device."

Is merely approving the device nearly enough? Do you really trust poorly educated, overworked, and underpaid TSA employees to properly calibrate, use, and maintain these machines?

Even with medical-grade x-ray technology that's FDA certified, and operated by way more qualified technicians than the TSA is ever likely to bother with has had accidents when massive overdoses of radiation have been administered... sometimes to lethal effect.

Re:TSA incompetence

[Anonymous Coward]

Yes, but medical radiation machines are designed to be able to put out more radiation in various ways. That's just their function, so as you stated it would be operator error that causes the accidents.

The TSA doesn't need variable radiation. They need it at exact X amount, radiated in Y space. X and Y will always be the same for every machine.

So if they can prove that a) X amount of radiation is safe, and b) the machines are built such that they're physically or mechanically incapable of putting out more than X radiation, then the backlash against them would be significantly less.

As you eluded to, most of the arguments against the machines tend to be centered around calibration, or "what if it puts out 50X radiation" type questions. If the answer is "it can't be calibrated, because it's only physically capable of emitting X radiation or less", then you drop that entire spectrum of complaints.

Re:Capitalisim [sic]

They're a cash grab for scanner makers, who are politically connected to the TSA.

eg Michael Chertoff, former Homeland Security secretary who shilled hard on the "need" to install full-body scanners, then later acknowledged that his consulting agency had a client that manufactured the machines. That is the kind of corruption one would expect in a third world tinpot dictatorship.

Photon is photn is photon

[aepervius]

All those radiation are in the same "nature" they are electromagnetic radiation, or better called photon. They differs in *energy* and thus in effect. Simplifying, Microwave will excite barely rotational level in molecules, Infra red is akin to vibrational levels in structure/molecules, and short infrared/color/UV is electron excitation from an outter shell level to another. Xray more or less is excitation from the inner core shell level. Gamma is even more, can only be gotten IIRC thru nuclear reactions. But they are the same in nature, only the different energy level and the quantic nature of matter make the effect different.

Re:Photon is photn is photon

As others said, alpha and beta radiation are not photons.

There is no completely safe lower limit

[Anonymous Coward]

There is no completely safe lower limit of ionizing radiation. It's a risk benefit situation. I'm not sure that the risks here are outweighed by the risks.
I don't order CT scans unless I think that the benefits far outweigh the risks, and I don't think that one should have to deliberate exposure to ionizing radiation.

Re:There is no completely safe lower limit

[vlm]

There is no completely safe lower limit of ionizing radiation. It's a risk benefit situation.

Actually no, you need to talk to a telecom EE about signal to noise ratios or a statistician or a nuke industry guy about banana equivalent dose.

Depending on who's fishy numbers you use, the BED of a ctscan varies a heck of a lot but is probably around a quarter million bananas depending on your bananas and your scanner. You're wise from a dosage perspective to not ctscan people for fun, but its not a terrifying risk nor certain death, its merely about ten extra lifetimes of eating bananas, depending on how many bananas you eat, no big deal as long as you don't do it annually for a lifetime or something.

On the other hand natural background in an airliner at altitude is about a dozen bananas per hour. This is below the long term lower noise boundary for an occasional traveler, but starting to be a signal above the noise for a typical airline pilot. Your total average natural background, again depending on who's fishy numbers, is surprisingly high at about 2 BED per hour. This makes concern about "no such thing as a lower limit" dosages under 50 BED per day or under 20 kilobananas per year extremely fishy to even discuss.

Given a decent scintillation detector or an old fashioned geiger I can detect precisely one individual atomic decay. We live, naturally, in a sea of radiation that's immense orders of magnitudes higher than the minimum we can measure, with a remarkably high standard deviation, making "no lower bound" nonsense to discuss from a noise perspective.

Re:Not just airport scanners

[blueg3]

The dosage is much less than the airport scanners. In that the dosage of ionizing radiation in airport scanners is nonzero (for X-ray backscatter type scanners) and the dosage of ionizing radiation in anti-shoplifting RFID detectors is zero. So, yeah, pretty different. I wouldn't worry about the effect, though. It's zero too.

Practically every mall store has a shoplift tag detector you have to walk through to get in and out of the store, although obviously the dosage is much less than the airport scanners. I'm a bit worried about the effect of those on the eyes.

The problem is there are actually several distinct devices:

Some us optical light, others use sonar, and the ones everyone is afraid of use x-ray.

Unfortunately, reporters can't be arsed to sort this out and just lump all the "naked picture machines" together assuming the underlying technologies are all equivalent.

Getting the core facts right...

[Shoten]

Okay, there are two kinds of body scanners. One uses backscatter x-rays, the other uses millimeter-wave radio waves. The ones deployed at airports are the latter, not the former; x-rays are not being used to scan people in airports in the United States. So let's recognize that what the TSA is doing here is evaluating a kind of scanner that they have not deployed . In other words, they're making sure it's safe before they use it. Backscatter x-ray scanners are more commonly used to examine vehicles; they produce a 2-d image rather than the 3-d representation you get from a millimeter wave scanner, so they aren't nearly as good at detecting hidden objects under clothing.

I hate the TSA at least as much as anyone else (I'm a frequent business traveler...so yeah...they are a huge pain in my ass between the security lines, the extra time needed, the restrictions on what I can carry, and the surly inspectors doing the "Uncle Touchy" routine), but facts are still facts, and in this case they haven't deployed first, tested later.

I travel every other week between LAX and SFO and both airports have removed the backscatter machines from security checkpoints I use. In addition to standard metal detectors, you will still find the older millimeter wave machines (the ones that give a simple red or green indicator) in some places.

It's nice not to have to go through the "opt out" groping routine on a regular basis any longer.

Re:For what it's worth

Yeah, I noticed that too. On a recent trip I was going to assert my privacy rights and refuse to go through the scanners. At both LAX and ORD, the scanners were sitting unused in closed lines, and people were being directed through the regular metal detectors.

Ok, but you have the core facts wrong.

[Gordo_1]

Up until a couple months ago, there were *both* backscatter X-Ray machines and millimeter wave machines in use in US airports. The backscatter X-Ray machines WERE NOT properly tested and WERE deployed FIRST. They're undoing that mistake now by removing the backscatter machines (at least from the airport checkpoints I frequent.)

I heard that the backscatter machines were being relegated to smaller airports, but I have no firsthand knowledge of that situation.

Re:Ok, but you have the core facts wrong.

[Natros]

I can tell you that Washington Dulles (IAD) airport, installed the Rapiscan backscatter machines in their brand-new security checkpoint that opened last year. They're still using them as of 2 weeks ago, and I've not heard any indication that they're planning to change to the millimeter wave detectors. That's a *very* major US airport, with a lot of people being exposed every day. Albuquerque (ABQ), on the other hand, uses the millimeter wave detectors, and that's a relatively small airport, even if it is the main one for its region.
