Abstract :
It is shown that the effect of large irradiation doses on scintillation properties is mainly connected with bubbles which grow due to irradiation-induced diffusion of created vacancies, the number of bubbles remaining approximately constant. To all appearance, some structure defects initially present in a crystal act as coalescence centers for vacancies. Under this assumption, a significant straggling of the examined samples in the sensitivity to gamma-irradiation can be attributed to the difference in the number of coalescence centers
