MarkeTech BGO (Bismuth Germanate, Bi4Ge3O12) Scintillator Crystal  (discontinued **)
Categories: Ceramic; Oxide

Material Notes: Bismuth germanate is intrinsic scintillation material with high absorption power. Due to its high effective atomic number and high density, BGO is a very efficient gamma absorber with high photo effect fraction which results in a very good photo peak to Compton ratio. BGO detectors are preferred for medium and high-energy gamma counting and high-energy physics applications.
