Radiation Shielding Properties of Bi₂O₃-Na₂O-B₂O₃ of 662 keV

Abstract

The bismuth sodium borate glasses in formula xBi2O3:20Na2O:(80-x)B2O3 (x = 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50 mol %) have been prepared by melt-quenching technique. The glass sample at x=0 mol% show the colorless and show the stronger yellow at the higher Bi2O3 content. The glasses’s colors are corespondening with the cutoff wavelength’s results. The shielding properties were measured at 662 keV by Cs-137 radiation source. The obtained results show that the mass attenuation coefficient increased with the increasing of Bi2O3 concentration. Half Value Layer (HVL) of glasses were determined and compared with the some standard shielding materials. The optical and physical properties were also investigated.
