The thermoluminescent dosimeters are widely used for measuring the radiation dose. However, the luminescence centers of thermoluminescent dosimeter are disappeared by reading process, and then repetition of measurement is impossible. Radiophotoluminescent glass dosimeters can be repeatedly read and keep the luminescence centers for a long time. The aims of this study are to develop and characterize the radiophotoluminescent glass dosimeter and measure the clinical radiation dose using Dose Ace system.
