Glass phosphors are broadly used to determine patient doses in radiation diagnostic and radiotherapy because of their good features, the dose ranges of interest are approximately0.1 -100 mGy for clinical x-ray diagnostics, and 1-5Gy for radiotherapy. Materials and Methods: Borate silica glass samples were prepared using melt quenching technique, XRD analysis confirms that the glass system is amorphous (non- crystalline). TL properties of glass were investigated such as optimum concentration, heating rate, and annealing procedure. The optimum glass samples of 45ZnO-45B 2O3-10SiO2 are used as glass radiation dosimeter. The samples were irradiated using 6MeV and 6MV photon beams in adose range (0.5-4) Gy. Results and Discussion: There is single and wide thermoluminescence glow curve that offering with maximum intensity at about 165 oC. Linear dose-response behavior has been observed in this dose range for both irradiation electron and photon beam. Sensitivity and minimum detectable dose have been found. The sensitivity of 6MeV is 1.7 greater than the sensitivity of 6MV photon energy. Conclusions: The results point out that this glass has the potential to be used as an electron and photon radiation dosimeter.
