Japan develops radiation detector for plastic bottles http: //

Japanese researchers use recycled plastic from beverage bottles to make sensors that can detect radiation, which can be used in radiation detectors, which is expected to reduce costs by 90%.

Assistant Professor Hidemura Nakamura of Kyoto University worked with Teijin to design a sensor made of PET material, which can be used to manufacture small radiation detectors and larger models of radiation reading measuring instruments.

PET, or polyethylene terephthalate, is widely used in plastic beverage bottles. The researchers used beverage bottles to make a plastic resin, and found that this material emits fluorescence when exposed to radiation, and has good strength, flexibility, and low cost. It can be used as a sensor in a radiation detector.

Currently, most of the raw materials for sensors on the Japanese market are imported from Saint-Gobain in France, and the price is relatively high.

Teijin's public relations department estimates that the sensor is priced at about 10,000 yen (about US $ 130), which is 90% cheaper than existing products on the market. It will supply some government departments and enterprises as early as next month.

Teijin Sales Director Ishii Toru told Reuters, "Our goal is to make the final product at the end of September", that is, the radiation detector, which will be used by government departments and enterprises for trial in September and October, and then gradually supplied to the public.

After the March earthquake and tsunami in northeastern Japan, the Fukushima Daiichi nuclear power plant leaked, and many people rushed to buy radiation detection devices.
