High Atomic Number BGO Scintillation Crystal Non Destruction Testing
High atomic number Non-Destruction Testing BGO Scintillation crystal
Bismuth germanate Bi4Ge3O12(BGO) is one of the most widely used heavy oxide scintillator materials. BGO has a high atomic number (83) of the heavy component Bismuth element and a high density(7.13g/cm3 )of the material. The luminescence spectrum of BGO scintillators has a maximum in the visible spectral range at 480 nm. Among advantages of BGO crystals, one should note their non-hygroscopicity, mechanical and radiation stability. BGO scintillators are stable under radiation doses of up to 103 rad.
Another important advantage of BGO crystals is a nearly complete absence of afterglow. The decay time of the main scintillation component of BGO at room temperature is 300 ns. All above advantages of BGO crystal makes it successfully used in experiments of high-energy physics, small-sized tomography devices and an active protection from background activity.
