Phoenix Airport to Use 'Backscatter' X-Ray on Travelers
Sky Harbor International Airport here will test a new federal screening system that takes X-rays of passenger's bodies to detect concealed explosives and other weapons. The technology, called backscatter, has been around for several years but has not been widely used in the U.S. as an anti-terrorism tool because of privacy concerns.
