WebBGO (Bi4Ge3O12) 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, BGO 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.
