Abstract: Gamma ray shielding properties of PbO-Al2O3 -B2O3and PbO-Al2O3 -SiO2 glass systems have been evaluated in terms of mass attenuation coefficient, half value layer, mean free path and effective atomic number parameters. Structural information of both the glass systems has been obtained by using density, XRD, DSC and ultrasonic measurements. It has been inferred that addition of PbO improve the gamma ray shielding properties and simultaneously decrease the rigidity of the glass systems due to formation of non bridging oxygen. Gamma ray shielding properties of our glass systems have been compared with standard nuclear radiation shielding concretes.
Keywords: Attenuation Coefficients, DSC Studies, Glasses, Ultrasonic Measurements.
