A controversial new X-ray technology is being tested that could stop potential terrorists from blowing up a car bomb at one of the nation's airports, homeland security officials in the US say.
The Transportation Security Administration (TSA) is running a test at a North Carolina ferry terminal of a 21-foot-high arch-like machine that shoots low-intensity X-rays at cars as they pass through. The photos show whether explosives or drugs might be in the car. Each vehicle takes approximately 30 seconds to scan – must faster than any previously deployed technology – and has the ability to scan occupants at the same time.
The technology, called backscatter X-ray, is in use at several airports to screen passengers. Privacy advocates have denounced scanning people as invasive because the X-rays can see through clothes.
