Japanese chemicals company Teijin has developed a plastic that emits a blue light when exposed to radioactivity (pictured). Named SCINTIREX, the company expects the polyester-based resin to be used as a scintillator, a core part in radiation meters (radiation quantity can be calculated based on the level of luminescence). Teijin developed the plastic in cooperation with Kyoto University and Japan's National Institute of Radiological Science (NIRS) and plans to market it to makers of radiation detectors wanting to push their costs down.
