The glass phosphor thermoluminescence (TL) properties of zinc borate silica (ZBS:45ZnO-45B(2)O(3)-10SiO(2)) doped with various concentrations of Cu2O and then co-doped with various SnO2 was analyzed. The doped sample with 0.005% Cu2O concentration and co-doped with 0.1 mol% SnO2 have a higher TL response among the other concentrations for a delivered dose 50 Gy of Cobalt-60 gamma radiation. The obtained glow curve from the optimum doped and co-doped samples with 0.005% Cu2O and 0.1 mol% SnO2 concentrations are simple with single glow peak. The annealing procedure and heating rate are determined for both optimum samples. TL response within the dose range of 0.5-100 Gy, minimum detectable dose, reproducibility and fading are investigated. Based on analyses of glow curve, linearity, reproducibility, dose threshold, thermal fading, optical bleaching and activation energy frequency factor, the glass with co-doped 0.1 mol% SnO2 found to be suitable as a thermoluminescence dosimeter.
