RPL Dosimetry: Principles and Applications

The principle of radio‐photoluminescence (RPL) is applied to the glass dosimeter, which is one of the most excellent solid state dosimeters. The silver activated phosphate glass irradiated with ionizing radiations emits luminescence when exposed to UV light. This phenomenon is called RPL. The most characteristic features of the glass dosimeters are data accumulation and no fading. The basic principle of RPL is described and then how it is applied to the glass dosimeter is explained. Finally some applications of RPL will be introduced.
