Abstract

Silver ion-activated phosphate glass (Ag⁺-glass) has a good potential for application to radiation dosimetry in various radiation fields due to its multifunctional properties as a detector. The Ag⁺-glass provides three independent signals of radiophotoluminescence, optical absorption, and nuclear track. The combination of these signals allows the dynamic range of the measured dose (10 μGy-10 kGy) and linear energy transfer (<10 keV/μm and >1 MeV/μm) to be widened.
