Abstract
In this study, the thermoluminescence dosimetric performances of a locally produced soda-lime-silica glass by the Saudi Arabian Glass Company Limited (SAGCO) were examined to evaluate its potential use in low-dose gamma-ray field. The samples were homogenously irradiated to different doses using a cesium-137 source. Some important characteristics of these glass dosimeters were investigated: The thermoluminescent glow curve exhibited a main peak at about 200 degrees C, the dose response curve showed a good linearity in the low-dose range 0-500 mGy, and the lowest detection dose was found to be 0.30 mGy. No substantial change (less than 6%) in the response of the dosimeters was found within incident angles of irradiation between +/- 60 degrees. A post-irradiation heating at 160 degrees C for 15 min before readout was found to be the most appropriate procedure for the elimination of the initial rapid fading.
