No radiation risk from airport scanners
Full-body scanners used for security screening at the nation's airports do not expose passengers to dangerous levels of radiation, according to a new independent analysis of the devices.
The study by the Marquette University College of Engineering concluded that radiation from so-called backscatter scanners passes beyond a passenger's skin to reach 29 organs -- including the heart and brain. But the radiation levels are considerably lower than those of other X-ray procedures such as mammograms, the study said.
