The effects of pre-irradiation annealing on the thermoluminescence glow curves of gamma irradiated alpha-Al2O3:C have been studied for measurements between 30 and 500 degrees C. In particular, the response of the main dosimetric peak has been studied for gamma irradiation doses between 0.1 and 440 Gy and that of a subsidiary higher temperature glow peak for doses between 0.1 and 200 Gy. The response is observed to be linear only at low doses in agreement with previously reported data. The type and density of defects that may contribute to the observed dose response at various stages of the growth curve are discussed. |
