Maine Senator Wants Independent Study of TSA's Body Scanners

OverTheGeicoE writes "U.S. Senator Susan Collins, the top Republican on the homeland security committee, plans to introduce a bill that would require a new health study of the X-ray body scanners used to screen airline passengers nationwide. If the bill becomes law, TSA would be required to choose an 'independent laboratory' to measure the radiation emitted by a scanner currently in use at an airport checkpoint and use the data to produce a peer-reviewed study, to be submitted to Congress, based on its findings. The study would also evaluate the safety mechanisms on the machine and determine 'whether there are any biological signs of cellular damage caused by the scans.' Many Slashdotters are or have been involved in science. Is this a credible experimental protocol? Is it reasonable to expect an organization accused of jeopardizing the health and safety of hundreds of millions of air travelers to pick a truly unbiased lab? Would any lab chosen deliver a critical report and risk future funding? Should the public trust a study of radiology and human health designed by a US Senator whose highest degree is a bachelor's degree in government?"

      1) The TSA keeps claiming we need these new and more intrusive security programs to catch terrorists. Yet, they haven't caught any.

      2) There really isn't any way to test the deterrent claim. Yes, you could have some random airports reduce security on the line to pre-911 levels. (Don't announce it and rotate daily which airports have these security reductions.) Then, you could test which flights had more instances of terrorist attacks. However, if the deterrent of the enhanced security is true, it would apply to the dropped security lines as well since the terrorists wouldn't know ahead of time which airports to target. In short, it's untestable unless you announce the reduced security airports ahead of time and nobody would authorize that.

  7. Measure Cost Efficiency by Bob9113 · · Score: 5, Interesting

    The single most significant missing component in all our security efforts is a cost analysis. Are we spending too much, too little, or about the right amount? Some say that measuring that is hard, and it is. But measurement is inherently approximation (there is no such thing as a ruler that is exactly twelve inches long). Once you accept that, it becomes much easier to measure lots of things (see also: How to Measure Anything).

    Can we begin with a very rough boundary estimate? I think we can. Here's one I did in my head while driving through the desert recently:

    I am willing to accept having two of my one thousand closest lifetime United States citizen acquaintances die in terrorist attacks. That is an acceptable risk level. If we can get there, I feel we have done all we need to do. By the same token, if we are spending any significant amount of money to go beyond that level, I am less supportive. I don't think it is worthwhile to catch every terrorist any more than it is worthwhile to catch every speeder or jaywalker. Two in one thousand, lifetime, sounds like about the right number.

    OK, so, how does that work out as an annualized US death toll? (please note: I did this in my head, and am mostly just regurgitating it here -- please correct me if the math is off)

    Desired Death Rate: 0.002 per lifetime
    Lifetime Length: 80 years
    Annualized Rate: 0.00002 risk per-annum per-person (equals 0.998 chance each person will reach 80 before dying from terrorism)
    United States Population: 300,000,000
    My Maximum Acceptable Annual U.S. Terrorism Deaths: 6,000

    I think we should be trying to stay under 6,000 United States citizens dying from terrorism every year. It is the acceptable rate, to me, in terms of the risk of my acquaintances dying. Any significant spending we do to get under that number is -- to me -- emotionalism, not rationalism. Given we haven't reached 6,000 in the past 20 years, I suspect we are spending too much.

Conventional wisdom on radiation safety is that the dangers are cumulative, but that's clearly not really the case. Maybe for long term risks like cancer, but clearly in the short term, higher intensity is more dangerous. For an extreme example, consider em radiation in the 560 to 490 nm wavelengths. Exposure is, as far as anyone has ever studied, virtually harmless. An entire lifetime's exposure adds 0% to cancer risk as far as I know. However, take a person's average exposure over the course of a month and give it to them in a tenth of a second. The cancer risk is still 0%, but that's only because the person has just been utterly vaporized. Maybe try instead taking a person's exposure to those frequencies in full sunlight over their whole body and concentrate it for 30 seconds on just one square centimeter of their body. No instant death this time, but that square centimeter will be completely and permanently destroyed. Also, cancer risk from that is now no longer 0% because of all of the byproducts from the burn.

      So, yes you get more radiation from the flight than you do from the body scanner. People forget that visible light is radiation too, of course. So, technically, you get far more radiation from the lights in the plane than you do from either of them. Radiation safety obviously has to take these things into account, and it gets technical. Maybe many of us here won't understand the deeper issues involved in a full technical explanation of the relative safety of the body scanners versus the flight.
