Physicists explore a safe alternative to X-ray security scanners
April 10, 2018, University of Sussex
A team of physicists at the University of Sussex are developing the science to create a safe and efficient 'paint' that can reveal, with terahertz (THz) radiation, the contents of luggage or objects hidden in clothing.
THz radiation could replace the use of harmful X-rays and ultraviolet light in security scanners. It cannot pass through water, which is why it does not pose a health risk to living tissue, but it can penetrate fabrics, plastics and wood to give internal images similar to an X-ray.
