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."
Really?
Where's the accountability?
We wouldn't want them to figure out that the scanners are hazardous until the contract to buy all those scanners has been fulfilled. You just know that some lucky contractor will make boatloads off of this.
I'm sure the radiation is totally safe. After all Curie died of old age after decades of labwork amirite?
To offset political mods, replace Flamebait with Insightful.
meanwhile, Europe bans them. A lot smarter than these fools running the US, g*d damn them. http://www.scientificamerican.com/article.cfm?id=europe-bans-x-ray-body-scanners
Earlier this month, a ProPublica/PBS NewsHour investigation found that the TSA had glossed over research that the X-ray scanners could lead to a small number of cancer cases.
Because cancer is clearly not a big deal. From another perspective, I wonder what dosage TSA agents get when they stand around those devices all day. I'm not particularly fond of them, but I wouldn't wish cancer on anyone. And these scanners are probably increasing their chances significantly. I wonder if anyone is up for conducting a large-scale clinical trial to show the low-level employees that these devices are hazardous and that they too should be against them.
When we let fear control us into letting an "elected" official create a cabinet department called the Commission for State Securit--err I mean Department of Homeland Security, even though WE ALREADY HAVE A NATIONAL GUARD AND A CENTRAL INTELLIGENCE AGENCY. Seriously, did someone miss the possibility of alterior motives when it was announced we were reinventing the wheel?
I'll have to find some sources, but didn't they refuse to allow the TSA employees to wear radiation exposure badges or something like that? (To determine if they were being over exposed)
They probably don't need to do any studies on if the scanners are safe or not, seems like they already know the answer.
If what I just said sounded like a troll, it was probably just a failed attempt at humor.
Weren't these scanners put in place for safety reasons? I.E. protecting people from harmful terrorists? Why do they want to protect us from harmful terrorists and not harmful cancers?
That's rude of the TSA. I have x-ray allergies you insensitive clods!
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. Because it would just be sheer stupidity to operate like that. (Of couse I expect a governemnt agencey to be operating within the stupidity realm).
Cancer risk, or terrorism... I mean, what's the harm in increasing - hypothetically, of course; they haven't proven it yet - a person's cancer risk when compared with the risk that, by not scanning everything and everyone, a terrorist will get on the plane and, absolutely, positively, undeniably cause that plane to crash into the building that causes the most deaths and financial damage?
Let's be reasonable, people... /snark
...There is such a thing as a middle ground.
These body scanners are on one end, having nothing is the other. I'd prefer something in the middle.
What do I know, I'm just an idiot, right?
And yet in all the months I've been running into these damn X-ray machines, I think I've only seen one other person opt out in favor of a pat down/groping session.
The rest of this country seems to be full of sheep.
If they actually did the study then Chertoff and Rapiscan would have to mount another FUD campaign to create a need for some other product that Rapiscan would make and Chertoff would convince all his friends in the government to buy.
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?
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?".
Questionable agency with questionable methods disapproves of mandate to test the questionable efficacy and questionable safety of their questionable equipment.
Seriously, is this a surprise? The public support for the intrusiveness of the tsa is dwindling rapidly, and a bombshell like "airport and transit station scanners linked with cancer" would set fire to that particularly nasty powderkeg.
Of course they want to ostritch headplant and hum to themselves rather than operate reputably! Their entire operation is a farce all the way down!
I don't blame you.
Signed, an American.
Back in the days of Tuskeege, the government thought it only get away with conducting deadly experiments on blacks. Later it figured it could get away with doing it to conscripted troops.
Now it has no problem doing it to us all.
Stop flying until the TSA is gone. Seriously.
Having to show your papers, take off your shoes, and choosing between having nudie pictures taken or having your genitals groped is what the U.S. has fallen to. It's no longer airlines. The TSA is beginning to make appearances at train and bus stations. If you don't take a stand now, when will you take a stand? When there's a uniformed officer standing in your bedroom feeling between your legs to make sure you're not a terrorist?
Given these machines have been BANNED in Europe for health concerns, let's put off doing the right thing....
Any one remeber Lead Based Paint? Banned in Europe in the 40's becuase of brain dammage... took till 1976 for the US to ban the crap...
I guess our Government has been eating some of those paint chips.
Repost cuz I can't stand being a coward:
Why is it that I can't just put one in my pocket and go through the machine to find out?
You know, For Science!
Does it include any metal? Sorry, bud, contraband. Off to the strip-search before Gitmo.
It's odd... I opt out and when I do the TSA employees are very, very helpful and friendly. I know that they have a strict script to stick to, but I also get the impression that they are not all that happy about the exposure risk, and are happy when others recognize the risks as well.

It appears that the more of the X-ray body scans you go through, the bigger your penis becomes and also the boobs become bigger.
Strangely enough both effects are detected in both genders.
You can't handle the truth.
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.
"I opened my eyes, and everything went dark again"
Also, you probably need to get both inside and outside measurements... if you could get a TSA worker by the machine to wear one in their pocket for a few weeks, that would be a very useful measurement.

Have gnu, will travel.
They're perfectly safe, but ball fondling causes cancer.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?

I don't read your sig. Why are you reading mine?
In order to protect our citizens from terrorism, we had to sterilize them.
Do not mock my vision of impractical footwear
My home airport, PDX, just announced they'll be fully deploying new scanners just in time for the holiday travel season (joy), and they are mm-wave RF. The waste of time and money still pisses me off, but at least I don't have to go through the PITA of opting out for safety reasons now.
Why not test the radiation levels yourself? Badge? Gizmo? Just walk through to get a reading, can we?
We're all about science here. Who's willing to risk it... For Science!

Well, for one thing, you'd have to go through the machine....
Can you be Even More Awesome?!
The TSA is an ecoterrorist ploy to sterilise the full popluation of polluting air travelers. This way they will not pass their polluting ways and genes on to the next generation. Combine that with the decrease in overpopulation and the poor, sick mother earth can recover! Kumbaya!
Well, I might have a way, but it only works on a semi spherical planet in a vacuum.
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.
How much longer are you going to tolerate this in the US? You are marching swiftly towards a completely corporate.fascist.militarist state and nobody seems to notice.
wow never mind... apparently you can get dosimeters on ebay. They even have some pen sized ones....
Apparently film is rare in the states these days. Though, it does provide a record, which is nice for this application.
"I opened my eyes, and everything went dark again"
Obvious statistical screwup is obvious - and constantly repeated by people with an irrational fear of weaponry.
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.
You can find GammaMaster radiation dosimeter wristwatches on eBay. They're expensive but they come calibrated and they look decent as well.
Slashdot's first reaction to VMware
You can buy the hexagonal medical ones quite cheaply, but you'd need to get someone to read it for you. However, they're probably not sensitive enough. You'd also need to control for factors like going outside, which can cause a detectable amount of exposure on a good dosimeter.
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.

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.
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.
He put his boots up on the table and made a face. "The sig," he smirked. "You can waste your life in search of the sig."
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?
