摘要：
Radiation resistivity of 4 x 4 x 30 mm(3) BGO crystals from three suppliers has been studied for doses 10(4) Gy (10(6) rad) and 10(5) Gy (10(7) rad). Radiation hardness was examined by the measurement of optical transmission through BGO crystals before and after (60)Co gamma-ray irradiations. The absolute degradation of transmission for 10(4) and 10(5) Gy doses at 480 nm wavelength of the peak emission of BGO, was found to be lower than 3.4% and 7.5%, respectively. The results have been also compared with radiation hardness measurements for a large volume circle divide30 x 30 mm(3) BGO crystal as well as another heavy scintillation crystals: fluorides and tungstates. Complete recovery of BGO radiation damage was observed only after few days. (C) 2003 Elsevier Science B.V. All rights reserved.
