Abstract
Spectrometric properties, such as light output, energy resolution BGO crystals before and after 60Co gamma-ray (dose 104 - 106 R) and neutron irradiation (fluence 1014 cm-2) are investigated. Condition for degradation of spectrometric properties and their recovering after irradiation are studied. The energy spectrum of the photons emitted from BGO crystals irradiated with neutron fluence contains the long living background peak which is caused by self-irradiation with radioactive isotopes produced in the crystals. The defect production was studied in crystals under the high dose gamma-irradiation with 60Co isotope. It was found that after doses above 108 R the color center at 365 nm and doses higher than 109 R a wide absorption band in the region of 300 - 350 nm occur. Comparison of these results with those of reactor irradiation has shown that under the high dose gamma-irradiation the structure defect production takes place.
