"Terahertz time-domain spectroscopy is a tantalizing technique for scientists wanting to characterize materials and for those charged with securing airports and other sensitive locations. Unlike X-rays, terahertz radiation—which lies above microwave wavelengths and below the infrared band, in the 30 micrometer to 1 millimeter range—doesn’t damage biological tissue and provides good resolution."/p?
