Exposing a Radiation-Hardened 2.4 GHz Wi-Fi Receiver to 500 Kilograys

AI-summarised brief · reviewed before publication

Japanese researchers created a radiation-hardened Wi-Fi chip that survived 500 kilograys of gamma radiation, a significant dose. The chip's design reduced transistors and used inductors, making it less sensitive to radiation. Despite degradation, the chip remained functional, with performance changes of 1.5-1.6 dB. This breakthrough could enable Wi-Fi use in high-radiation environments, such as the Fukushima Daiichi nuclear reactor, and has implications for space exploration and radiation-rich areas.
