Radiation Detection: plastic materials, such as developing a glowing blue Univ.
(RadiationAlerts.org note. If this product was made into packaging for water, foods, even clothing, then today's issues, this invention has a big market.)

A plastic material that glows blue when radiation hits, Kyoto University and NIRS, Chiba, developed by Teijin team. "Cinch Rex" was named. Cheap and easy to process the advantages are expected to be applied to carry dosimeters, which aims to commercialize this fall. 29, Journal of the European Physical Society Bulletin (electronic version) was released.
Conventional radiation detector has been used to give substance when exposed to visible light radiation. Some use a plastic detector is a special process in order to give light, the production cost that it takes tens of thousands to several hundred thousand yen.
Nakamura of Kyoto University Research Reactor Institute, Assistant Professor Hidehito team (radiation physics) last year and discovered that can detect the ultraviolet radiation hits the bottle on the market. Determine the sensitivity to radiation that is involved in the oxygen contained in the plastic was prepared by adding improvements.
Performance is comparable to or larger than the conventional product, alpha, beta radiation, gamma rays capable of. The process can be easily mass produced, is reduced to one-tenth the cost of manufacturing. Measure the internal exposure "whole-body counter" that can be applied to large equipment such as.
Assistant Professor Nakamura, "The impact of the first nuclear accident in Fukushima, which is required close to the radiation detector. Want to hang on the application of radiation detectors, such as mobile phone straps," he said. Yuka Saito]]
