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.
