(Reuters) - A Japanese researcher has come up with inexpensive radiation detectors made from the same resin as PET bottles to meet growing demand after Japan's March earthquake and tsunami set off the world's worst nuclear accident in 25 years.
The detectors devised by Hidehito Nakamura, an assistant professor at Kyoto University in western Japan, in cooperation with Teijin Chemicals Ltd, cut costs by 90 percent from existing devices, many of which come from foreign firms.
