'After years of using full-body scanner devices that emit radiation, the TSA is testing a new technology dubbed terahertz to screen multiple airport passengers at the same time, from a distance of up to 25 feet away, LA Times reported.
The technology, described as “passive terahertz” screening, is said to be “radiation-free,” according to Kevin Gramer, vice president of Thruvision Americas, the producer of the new invasive technology.
“It’s 100% passive. There is no radiation coming out of our device,” Gramer told LA Times. “You don’t have to stand directly in front of the device.”
The new device aims to scan the outline of a passenger to reveal firearms, explosives and other illicit material.
The terahertz scanners are so efficient that they can seemingly scan 2,000 people an hour and detect a concealed device at a distance of up to 25 feet, according to the report.
Already these scanners are being used to replace traditional radioactive full-body scanners, while further expanding the surveillance state to include subways now. Unsurprisingly, these devices are being installed in LA subway transit systems, with train stations all over the U.S. expected to follow in suit.
“The machines scan for metallic and non-metallic objects on a person’s body, can detect suspicious items from 30 feet (9 meters) away and have the capability of scanning more than 2,000 passengers per hour,” according to the Associated Press.
Signs will be posted at stations warning passengers they are subject to body scanner screening. The screening process is voluntary, according to Alex Wiggins who runs the Los Angeles County Metropolitan Transportation Authority’s law enforcement division said. However, customers who choose not to be screened won’t be able to ride the subway.'
