Reo Yamada's doctoral thesis, 'Enhanced bulk-etch-rate of gamma-irradiated PADC detector expressed by the radiation chemical yield of hydroxyl group' , has been published in the academic journal 'Radiation Measurements'. PADC is a plastic developed for spectacle lenses, yet it also serves as a radiation detector utilised for cosmic ray exposure management aboard the International Space Station. This research elucidates the molecular-level differences in the effects produced by protons (hydrogen nuclei) and gamma rays (high-energy electromagnetic radiation) on PADC. It describes results that are also useful for developing plastics with higher performance.
