Security checkpoints at major airports are missing something lately: X-ray scanners operated by the Transportation Security Administration, according to ProPublica.
The TSA is replacing X-ray body scanners with machines that produce less radiation, the investigative journalism Web site reported. The X-ray scanners are being moved to smaller airports.
The X-ray scanners were swapped out at airports including Logan in Boston, and airports in Los Angeles, Chicago, New York City and Orlando, ProPublica reported. San Francisco International Airport, Oakland International Airport, and Norm Mineta Airport in San Jose were not on the list.
The X-ray scanners produced criticism for the TSA following the "failed underwear bombing" of Christmas Day 2009, the news site reported. The x-ray scanners produce radiation, which has been linked to cancer at higher levels, and also produce a blurred image of passengers' naked bodies.
The new scanners use radio waves akin to those produced by cell phones, and allow the passengers to move through security more quickly, ProPublica reported.
