Naked x-rays

Isn't it sad, people worrying about an anonymous airport security staff member seeing a very fuzzy image of them almost naked in the interests of airport safety. People have said it is "horrible" to have such machines. Child protection legislation has been invoked to prevent children going through the scanners on the grounds the images may be "indecent". I wonder how decent it is to have those children in thousands of pieces after an aerial explosion. In a society that uses ever clearer and better images of violence as part of daily entertainment, such an idea to me is very odd indeed. What is worrying, no-one yet has asked how safe these machines are from the radiological point of view. We hear that no dose of ionising radiation is safe, so how about aircrew that may have to go through these things on a daily basis? The news is dominated by a few prudes concerned about nudity, what about safety from x-rays and nutters bent on destruction?
