Ezz El-Din, N. El-Alaily, H. El-Batal] The densities and refractive indices of some sodalime-silica glasses with replacements of CaO by either BaO or ZnO have been studied before and after being subjected to varying doses of γ-irradiation. Also, the effect of varying the Na2O or Al2O3 content was investigated. The experimental results show that γ-irradiation produces a slight change in the density but a remarkable increase in the refractive index. These data are correlated with the way of housing of the cation introduced into the glass and its response on the compactness and flexibility of the glassy network. Also the effect of interaction of γ-rays with the glass and the creation of new induced defects in the glass network, which might affect the properties investigated, is considered.
