    Study on Radiation Damage of Chinese-made High-ZScintillation Crystals

    • Institute of High Energy Physics, Chinese Academy of Sciences, Beijing

      Abstract:Radiation damage effects of several Chinese-made high-Zscintillation crystals have been studied on a60Co irradiation unit of 100 kCi. Results on small size BGO crystals irradiated by60Co γ-rays with various doses from 5×103to 7.5×105rad are presented. The non-linear decrease of the scintillation light output with the increase of the dose applied and saturation effects have been observed. The spontaneous recovery of the light output can be described by the sum of at least three exponential functions. The radiation damage effects of small size BaF2, CsI(Tl) and ZnWO4crystals at 5×105rad were also investigated. Serious damage to BaF2has been found. Preliminary analyses indicate that this may be attributed to the inclusion of certain critical elements, in the crystal. CsI(Tl) after irradiation does not exhibit strong afterglow or noticeable coloration as were reported in the literature.
