Abstract
Gamma ray buildup factors and fast neutron removal of Te2O3 doped WO3: Gd2O3: B2O3 glass systems were estimated. The buildup factors values were determined for photon energy 0.015–15 MeV up to penetration depths of 40 mfp (mean free path) by the geometrical progression (GP) method. The EABF and EBF values were found dependent upon photon energy, penetration and Te2O3 content. In low and high photon energy ranges, the EABF and EBF values were minimum whereas maximum in intermediate energy range. The fast neutron removal cross sections were computed by the partial density method. The glass systems with 2.0 mol% Te2O3 is found to be superior gamma ray and neutron transparent shielding. The results indicate that this glass can be used as radiation shielding material.
