BGO Scintillator Crystal High Z Density
High Z, high-density scintillation material BGO Scintillator Crystal
BGO is a high Z, high-density scintillation material. Due to the high atomic number of bismuth (83) and the material's high density of 7.13 g/cm3, it is a very efficient gamma-ray absorber. Given the high Z value of the material, the photo fraction for gamma-ray absorption is high and as a result, very good peak-to-total ratios are observed.
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; large-size single crystals are possible to obtain. Due to these features, BGO crystals are used in high-energy physics (scintillators for electromagnetic calorimeters and detecting assemblies of accelerators), spectrometry and radiometry of gamma-radiation, positron tomography.
