Description

CaSO4:Dy thermoluminescence dosimeter is one of the best materials for environmental and personal dosimetry due to its high sensitivity and high dose saturation. In this investigation, the dose response of CaSO4:Dy with three concentrations, 0.11, 0.15 and 0.2 mol % of dysprosium, to 60Co gamma rays doses up to 3.7 Gy were studied. The effect of heating program on glow curve was also studied. The glow peaks of CaSO4:Dy were seen at 100degC and 167degC. The pellets have high sensitivity and in the case of sample with 0.2 mol % of dysprosium, the relative sensitivity is 12. The dose response is found to be linear up to 3.7 Gy and the fading was approximately about 36 percent in 10 days.
