BGO (Bi4Ge3012) is an oxide type scintillation material. It has high atomic number and density. BGO has good property including strong mechanical strength, non-hygroscopic, no cleavage. Extreme high density 7.13 g /cm3 which makes these crystals very suitable for the detection of natural radioactivity.
BGO detectors are characterized by high energy resolution in the energy range 5 - 20 MeV, a relatively short decay time. Its parameters remain stable up to the doses of 5 x 104 Gy. Due to these features, BGO crystals are used in high-energy physics, spectrometry and radiometry of gamma-radiation, positron tomography nuclear medical imaging industry.
