GERMAN researchers have developed a method of accurately measuring terahertz radiation rays, so that this radiation can safely be used in new airport security detection machines. Scientists have long known the potential of using these so-called T-ray scanners: while metal or X-ray detectors usually identify just a few obviously dangerous materials, T-rays are far more sensitive and can identify many more illegal or dangerous substances.
