JOHN ROACH: Are Airport X-Ray Scanners Harmful?

Peter Rez, a physics professor at Arizona State University in Tempe, did his own calculations and found the exposure to be about one-fiftieth to one-hundredth the amount of a standard chest X-ray. He calculated the risk of getting cancer from a single scan at about 1 in 30 million, “which puts it somewhat less than being killed by being struck by lightning in any one year,” he told me.
