Abstract

The aim of this research is to study the radiation shielding and elastic moduli of Gd3+ on Ce3+/Tb3+ co-doped some scintillating glasses. The mass attenuation coefficients (mm), of scintillating glasses have also been computed in the energy range 1 keV – 100 GeV using WinXCOM software program. The effective atomic number (Zeff), effective electron density (Nel) and half value layer (HVL) have been computed. The lower values of HVL indicate that the scintillating glasses possess better shielding properties. The oxygen packing density (OPD), molar volume (Vm), number of bonds per unit volume, average cross-link density and packing density have also been obtained. The modulus of elasticity for samples are calculated by Makishima and Mackenzie mode and compared among themselves. The GTC15 scintillating glass has highest value of elastic modulus.
