Abstract
A lithium borate thermoluminescence dosimeter with 0.3 wt% of manganese impurity
concentration was prepared for high dose levels in the range of 1-30 kGy for gamma irradiation applications.
The TLD reader was used for read out purposes from ambient temperature to about 400°C with a heating rate
of 6°C/sec. The pre- and post- irradiation anneal temperature was 300°C for 1.5 and 1 hours respectively. The
effects of absorbed dose, dose rate, storage time, as well as the temperature and humidity versus pre- and
post-irradiation storage time have been studied. The main glow peak was found to occur at 375°C, and the
dosimeter response in the range of 1-30 kGy was linear. No significant fading effect of the dosimetric peak
was observed after 8 weeks of storage, and the effects of ambient temperature and humidity were less than
±5% at 95% confidence level.
