New X-ray Scanners Arrive at Airports

The hapless underwear bomber failed to blow up an airplane last Christmas, but the U.S. Congress nevertheless ordered 450 new full-body scanners that rely on X-ray backscatter to detect objects hidden under clothing. The first units are just now being set up at airports in Boston, Chicago, and elsewhere. Technology journalist Neil Savage explains how the new scanners work and whether passengers should worry about the additional exposure to x-rays.
