Abstract :
Radiation hardness of a 4×4×24 cm3 PbF2 crystal has been studied for doses up to 105 Gy. Radiation resistivity was examined by the measurement of optical transmission through the lead fluoride crystal before and after gamma-ray irradiations. The results have been compared with radiation hardness measurements for a 4×4×40 cm3 Pb-glasses SF5 and SF6 and a 3×3×6 cm3 CeF3 scintillation crystal, as well. Complete recovery of radiation damage was observed a few day after the irradiations.
