The radiation shielding and optical properties of xBi(2)O(3):(100-x)SiO2, xPbO:(100-x)SiO2 and xBaO:(100-x)SiO2 glass systems (where 30 <= x <= 70 is the composition by weight%) have been investigated. Total mass attenuation coefficients (mu(m)) of glasses at 662 keV were improved by increasing their Bi2O3 and PbO content, which raised the photoelectric absorption in glass matrices. Raising the BaO content to the same fraction range, however, brought no significant change to mu(m). These results indicate that photon is strongly attenuated in Bi2O3 and PbO containing glasses, and but not in BaO containing glass. The results from the optical absorption spectra show an edge that was not sharply defined; clearly indicating the amorphous nature of glass samples. It is observed that the cutoff wavelength for Bi2O3 containing glass was longer than PbO and BaO containing glasses. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.
