BGO Scintillator Crystal Effective Atomic Number 83
Density 7.13g/cm3 Effective Atomic Number 83 BGO Scintillator crystal
BGO scintillator crystals have the following issues which should be noted. They:
- Have a light emission which a is good part is above 500nm, a region where photomultipliers are less sensitive
- Are intrinsically radioactive making it unacceptable for some applications
- Are susceptible to radiation damage, starting with doses between 1 and 10 Gray (10² - 10³ rad). Reversible with time or annealing.
