The US Transport and Safety Administration (TSA) announced that it has removed all X-ray backscatter-based full-body scanners from US airports.
The TSA said that it met the June 1, 2013 deadline set by the US Congress to remove all the 250 body scanners.
While the X-ray backscatter-based machines have been removed, passengers will continue to undergo full-body scans with scanners based on other technologies such as millimeter-wave systems. These machines produce less detailed images of scanned subjects and are also relatively more safe than backscatter scanners.
The X-ray backscatter scanners had been controversial since their introduction due to privacy concerns. The TSA decided in January to retire the scanners as Rapiscan, the scanner manufacturer, expressed its inability to implement privacy-protecting features by the June 1 deadline.
