Effects of WO₃ on Radiation Shielding Properties of WO₃–TeO₂ Binary Tellurite Glass System

Abstract

In this research, a series of (100–x)TeO₂–xWO₃ glass systems (where x = 0, 10, 20, 30, 40 and 50 mol%) have been simulated in terms of radiation shielding behaviors. The simulation of mass attenuation coefficients (μ_m), effective atomic numbers (Z_eff) and effective electron densities (N_el) were calculated by WinXCom software program at energies ranging from 1 keV–100 GeV. The method of geometric progression (G–P) fitting has been used to calculate at wide energies ranging from 15 keV–15 MeV and up to 40 penetration depths (mfp) for buildup factors: exposure and energy absorption buildup factors (EBF and EABF). The simulated data reports that WO₃ partial replacement of TeO₂ in glass system (100–x)TeO₂–xWO₃ which increases behavior of radiation attenuation and 50TeO₂–50WO₃ showed the best shielding properties and potential to use as a transparent shielding material.
