Description

Radiation resistance of 4x4x30 mm3 GSO and LSO imaging scintillation detectors has been studied for low-energy gamma-ray doses of 104 Gy (106 rad) and 105 Gy (107 rad). Radiation hardness was determined by the measurement of optical transmission through GSO and LSO scintillation crystals before and after irradiations with 60Co gamma-rays. The results have been analysed in terms of the radiation-induced absorption coefficients and compared with radiation sensitivity measurements of small BGO scintillation crystals. The recovery time of irradiated small GSO and LSO crystals has also been determined
