BGO Scintillation Crystal
BGO (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.
Application
1 ) Positron emission tomography (PET)
2 ) High energy physic
3 ) Anti-Compton shield
4 ) Security scanning
Features
1 ) High Z
2 ) Good photopeak to Compton ratio
3 ) Scintillator of choice for neutron activation analysis and active Compton shields
4 ) High density
