Backscatter X-Rays Coming to Airports

TSMABob writes "Wired News reports that a recent, but expensive, technology of backscatter may grace airport security in the future. Nice Bombs Ya Got There is an article that explains how this technology is far superior to the metal detectors of today, pointing out that 'Richard Reid, convicted of trying to blow up a trans-Atlantic jetliner with explosives in his shoes, walked through metal detectors at Orly Airport in Paris several times before boarding the plane.' Read More about backscatter x-rays and their ability to pick up non-metallic objects."

      From the perspective of a Niel Stephenson reader, think of this as a x-ray frequency varient of milameter radar.

      What this does is send extreamly low dose x-ray radiation in the direction of the subject being scanned. Some percentage fo the x-rays (being extreamly high energy, even if it is low dose) will pass through the subject. Some percentage will be absorbed by the subject. Some other percentage will be reflected by the subject.

      A percentage of the reflected x-rays will be captured by an x-ray sensitive varient of a CCD and an image will be created by a computer.

      The demonstrations so far indicate that x-rays for the most part are passing right through clothing, and being reflected by the skin of the subject. Harder objects (such as plastic and metals) are either going to absorbe a higher percentage than usuall, or reflect a higher percentage than the subject, and will present visable difference in the image collected.

      Some training will be required, however most weapons are going to be fairly visable to this equipment.

    According to the FAQfor one of these machines...
    Q: How much radiant energy is a person exposed to?

    A: Each full body scan of the SECURE 1000 produces approximately 3 microREMs of emission. This is equivalent to the exposure every person receives each five minutes from naturally occurring background environmental radioactivity.

    Q: Is background radiation exposure really a good comparison?
    A: Yes, because SECURE 1000 scanning and background radiation both expose a large portion of the body to a very low level of x-rays. The only difference is that background radiation has slightly higher x-ray energy resulting in deeper penetration.

    Q: What about exposure levels for individuals who are frequent flyers or for employees in companies or high security facilities who have to be screened each day?
    A: Under current international guidelines (such as the ANSI 43.17 Standard) up to 5000 scans per year can be conducted safely.

    Q: Will SECURE 1000 detect objects in the body?
    A: No, the x-rays penetrate only about 1/10 (0.1) inch of the skin. Any object that would be deeper than that level would not be detected. Under current regulations generally body cavity inspections must be performed by high dose medical x-ray systems in the presence of a medical professional or body cavity searches must be performed manually by trained enforcement personnel.
