Abstract
The main aim of this work is to investigate the gamma ray shielding properties of ternary TeO2-WO3-PbO glass system. WinXCom software was used to calculate; mass attenuation coefficients (mu/rho), effective atomic numbers (Ze(ff)) and mean free path (MFP) for total photon interaction in the energy range of 1 keV to 100 GeV. For the purpose of this study this energy range was divided into three sub ranges, low, medium and high. PbO percentage in the tellurite glass contents was found one of the main reasons behind the change of values of mu/rho and Ze(ff). The tellurite glass with 40mol % PbO is found superior gamma-ray shielding. The obtained results of the selected glass systems were compared, in terms of MFP with some common shielding concretes in order to test the validity of these glass systems with respect to the radiation shielding. The shielding efficiency of the selected glasses is found better properties wise to that of common ones. The investigation was carried out to clarify the possibility of tellurite glasses to be used in different radiation shielding applications.
