Futurity -- CORNELL (US) — Terahertz radiation—currently used in airport body scanners—could prove instrumental in a wide range of medical and science applications, from detecting cancer and tooth decay to inspecting food through packaging. Terahertz’s range of wavelengths—between microwaves and infrared light—are able to penetrate cloth, paper, and leather and a very short distance into the skin—all without the damaging effects of X-rays and are also able to detect unique signatures of explosives.
