The BBC has reported that unlike traditional scanners which emit X-rays and “active” radiation, the T8000, developed by UK-based ThruVision Systems, uses a “passive” screening technology.
ThruVision’s scanners do not “illuminate” people with X-rays, radiation or millimeter waves. Instead, they receive terahertz waves naturally produced by objects and people. When a concealed object blocks those waves, it appears as an anomaly.
The materials that can be detected by the T8000 include weapons, explosives, liquids, gels, ceramics and narcotics.
One other upside to this new technology is that it doesn’t capture or display intimate body details which have been a concern for many travellers in the past.
Rapid screening time
No need to enter into a small confined space
Although not permanently implemented yet, these scanners have had positive results; successfully spotting contraband substances on test subjects.
