In this work were studied the thermoluminescence (TL) and optically stimulated luminescence (OSL) dosimetric characteristics of Ge 30As 4S 66 chalcogenide glass doped with Dy 2O 3 at various concentrations. The material displayed good sensitivity for β-irradiation and showed that TL and OSL signals are dependent on β-irradiation dose and Dy 2O 3 content. The dosimetric characteristics of Ge 30As 4S 66 glass specimens were read from the TL β -dose response curve, which showed a reasonably good linearity behavior between glow peak areas and β -dose values. Due to its encouraging characteristics such as acceptable batch homogeneity and good measurement reproducibility, the Ge 30As 4S 66 chalcogenide glass can be considered as a candidate material for dosimetry in the range from 0.5 to approximately 100 Gy. |
