In this work, the total mass attenuation coefficients of the
glasses increase with increasing Bi2O3 and PbO
concentration because of increasing photoelectric absorption
interaction of all glass samples. The total mass attenuation
coefficients of the Bi2O3 glasses and the PbO glasses are
comparable. This indicates that Bi2O3 can be used for
radiation shielding glasses. For the BaO glass, although there
was no significant change in the mass attenuation coefficient
values with increase of BaO concentration, the glass exhibits
a better shielding property like half value layer (HVL) than
ordinary concretes and commercial windows. The Bi2O3 and
BaO glass will open new possibility for a lead-free radiation
protecting glass with non-toxicity to our environment.
