Airport Security Technology

The mm-wave scanner uses radio waves to produce a 3D image and can detect both metallic and non-metallic items, while the backscatter scanner uses low-power ionizing X-Rays to produce 2D images.

The scanners can detect liquid and plastic explosives, ceramic weapons, illicit drugs, and other materials that are unidentified by metal detectors.

The mm-wave scanners are restricted to produce less energy than a cell phone and the backscatter X-ray exposure is equivalent to about 2 minutes of flying. Some countries allow opt-out options, especially for pregnant women.
