Description

Bismuth germanate (Bi4Ge3O12,BGO) 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. It is the most common oxide-based scintillator.
BGO is used in detectors in particle physics, aerospace physics, nuclear medicine, geology exploration, and other industries. BGO arrays are used for gamma pulse spectroscopy. BGO crystals are also used in positron emission tomography detectors. BGO detectors are preferred for medium and high-energy gamma counting and high-energy physics applications.


Features:
Dense and high absorption coefficient for gamma-ray.
High light output and short decay time, colorless and clear
Excellent energy resolution and uniform light output.
Small decrease in light output at 100°C
Almost no degradation in scintillation properties at 10*6 gray.
