Abstract

Abstract In this paper we present the scintillation properties of polished Bi4Ge3O12 (BGO) crystals grown by the Bridgman method. The light yield (LY) and energy resolution were measured using XP5200B photomultiplier. At 662 keV γ-rays, high LY of 9680 photons/MeV and good energy resolution of 8.6% were obtained for a 5 × 5 × 1 mm3 BGO sample. The intrinsic LY and light loss coefficient were evaluated. The photofraction in pulse height spectrum of 662 keV γ-rays and the mass attenuation coefficient at 59.5 and 662 keV γ-rays were also determined and compared with the theoretical ones calculated using the WinXCom program.
