A new study of the backscatter full-body scanners — the type installed for security screening at Sea-Tac airport and some other U.S. airports — has concluded the radiation risk is negligible even for children, frequent fliers and pilots.
The study by Marquette University College of Engineering, believed to be the first independent review of the X-ray scanners, found that the radiation passes beyond a passenger's skin to reach 29 organs — including the heart and brain, but at a level considerably lower than those of other X-ray procedures such as mammograms.
Sorry, but this doesn't make me feel any better, so I'll continue to opt out and go for the pat-down instead.
