Researchers at the Institute of Science, Tokyo, have developed a new 2.4 GHz Wi-Fi receiver chip capable of withstanding ultra-high radiation doses of up to 500 kilograys (kGy). The goal of this new chip is to solve the cable problem at sites like Fukushima Daiichi, where restrictive wiring currently prevents multiple robots from working efficiently in hazardous areas. “Such tolerance addresses the requirements of nuclear power plant decommissioning, which involves exposure to intense gamma radiation emitted from fuel debris,” said Atsushi Shirane, Associate Professor.
