Abstract

The objective of this study is to investigate the emission mechanism of radiophotoluminescence (RPL) in the Ag⁺-doped phosphate glass (glass dosimeter), which is now used as individual radiation dosimeter, because the emission mechanism of RPL in glass dosimeter has been not fully understood. We have investigated the assignments and characteristics of the X-ray induced colour centres in the Ag⁺-doped phosphate glass up to now (Miyamoto et al., 2010). Optical properties such as optical absorption spectra related with X-ray and α-particles irradiation were measured for commercially available glass dosimeter. In this study optical properties such as optical absorption spectrum as a function of X-rays and α-particles irradiation were measured for commercially available glass dosimeter. Comparison of the RPL in Ag⁺-doped phosphate glass irradiated with X-rays and α-particles is discussed.
