BGO Scintillator Crystal for Radiation Scintillation Detector

Description: 4.65X6.25X30mm BGO Crystal Pixel. Each crystal pixel has one small face smooth polished, and the sides and other face are either polished or have one or more sides prefinished with a texture. Select the variation you prefer. BGO is a Premium Scintillator Material and guaranteed to work for radiation detection when coupled to a PMT and built into a probe. BGO is dense, with a specific density of 7.13 g/cm^3 that provides excellent stopping power for high energy photons. Much greater density than that of NaI(Tl) and is non-hygroscopic and safe to handle. Great for high-energy physics experiments. These crystals typically sell new at a price of $50 each. Dimensions each crystal:Length = 30mm Sides = 4.65mm X 6.25mm Weight = 6.22gm Please check my other listings for LYSO and GSO crystal pixels. From the Manufacture:Bismuth Germanate (BGO) is a high Z, high density scintillation material with chemical composition Bi4Ge3O12. Due to the high atomic number of bismuth (83) and its high density, BGO is a very efficient γ-ray absorber. BGO is a relatively hard, rugged, non-hygroscopic crystal which does not cleave. The material does not show any significant self-absorption of the scintillation light. The crystal housing can be simple since no hermetic sealing is required. The scintillation emission maximum of BGO is situated at 480nm.
