Whatever else is true, the TSA is demonstrably lying about the safety of those backscatter machines. A large part of their claim is that the radiation penetrates clothing, but not skin.
Their own sample images prove this false: leg bones are clearly visible.

compilerbitch's post also discusses different kinds of radiation, and how little is known about the effects of some of them. (Comparisons of the relative danger from those machines and from cosmic rays are meaningless if we don't actually understand the danger of cosmic rays.)
