High levels of radiation would modify the optical properties of silicon in the devices, leading to incorrect readings. NIST test results indicate the sensors could be customized for measuring radiation dose in both industrial applications and clinical radiotherapy. Researchers at NIST examined the impact of cobalt-60 γ-ray radiation up to 1 megagray (MGy) absorbed dose on silicon photonic devices. They did not find any systematic impact of radiation on passivated devices, indicating the durability of passivated silicon devices under harsh conditions…read more. Open Access TECHNICAL ARTICLE
