摘要

In this study, the shielding properties of bismuth lead germanate (BPG) glass system incomposition x(Bi2O3)40-x(PbO)60(GeO2) where x = 0 to 40 mol% have been investigated.The shielding parameters, mass attenuation coefficients(μ/ρ), mean free path (MFP) andhalf value layer (HVL) values have been computed using WinXCom program andvariation of shielding parameters of the BPG glasses are discussed for the effect of photonenergy and Bi2O3 addition into the glasses. The replacement of PbO by Bi2O3 causes anincrease in mass attenuation coefficient, while the MFP and HVL values were decreased.The investigation would be very useful for shielding applications in nuclear technologies.
