Abstract

Abstract: Gamma ray shielding properties of 80TeO2 –5TiO2 –(15−x) WO3 –xAn Om glasses, where An Om is Nb2 O5 = 0.01, 5, Nd2 O3 = 3, 5 and Er2 O3 = 5 mol% have been achieved. Shielding parameters; mass attenuation coefficients, half value layers, and macroscopic effective removal cross section for fast neutrons have been computed by using WinXCom program and MCNP5 Monte Carlo code. In addition, by using Geometric Progression method (G-P), exposure buildup factor values were also calculated. Variations of shielding parameters are discussed for the effect of REO addition into the glasses and photon energy. Highlights: The shielding properties of 80TeO2 –5TiO2 –(15−x) WO3 –xAn Om glasses were evaluated. WinXCom program and MCNP simulation codes were used in the calculations. Good agreement was noticed between the WinXCom and MCNP5 code results.
