In this work, the mass attenuation coefficients and shielding parameters of borate glass matrices containing
with Bi2O3 and BaO have been investigated at 662 keV, and compare with PbO in same glass structure.
The theoretical values were calculated by WinXCom software and compare with experiential data. The
results found that the mass attenuation coefficients were increased with increasing of Bi2O3, BaO and
PbO concentration, due to increase photoelectric absorption of all glass samples. However, Compton scattering
gives dominant contribution to the total mass attenuation coefficients for studied glass samples.
Moreover the half value layers (HVL) of glass samples were also better than ordinary concretes and commercial
window glass. These results reflecting that the Bi-based glass can use replace Pb in radiation
shielding glass. In the case of Ba, may be can use at appropriate energy such as X-rays or lower.
