Effect of tungsten on radiation attenuation features of yWO3–(90 − y)TeO2–10Na2O glasses.

In this investigation, the photons shielding factors for tungsten tellurite glasses with the yWO₃–(90 − y)TeO₂–10Na₂O (y = 05, 10, 15 and 20 mol%), were reported. The penetration and attenuation factors for this system at various energies were reported using the Phy-X/PSD program. With increasing energy, it is observed that the linear attenuation coefficient (LAC) values, which range from 1.087–0.234 cm⁻¹ (for TWN1) to 1.354–0.248 cm⁻¹ (for TWN4), decrease exponentially. The LAC values were found to increase with the addition of WO₃ from 1.087 to 1.354 cm⁻¹ at 0.245 MeV and from 0.515 to 0.586 cm⁻¹ at 0.444 MeV. Additionally, the greater potential for photon interactions at higher WO₃ concentrations was indicated by the findings of the effective atomic number (Z_eff) calculation. According to the obtained results, the maximal Z_eff occurred at 0.284 MeV, which is equivalent to 32.53 for TWN1 and 36.89 for TWN4. The half value layer (HVL) for the samples under consideration between 0.245 and 1.458 MeV has been determined using the Phy-X/PSD. The HVL results demonstrated that at 0.284 MeV, more gamma rays are shielded whereas the potential of photon shielding decreases as energy increases. The tenth value layer (TVL) increased with rising energy and decreased with rising WO₃ concentrations. TVL for TWN4 is the lowest (1.701 cm at 0.245 MeV and 9.284 cm at 1.458 MeV).
