Gamma ray shielding properties of PbO-B2O3-P2O5 doped with WO3

In this study, WO3 based glass system in composition (100-x)[0.1B2O3-0.4P2O5-0.5PbO]-xWO3 where x = 10, 20, 30, 40, 50 and 60 mol% were prepared for gamma ray shielding properties. The emitted gamma ray has been detected by 3 × 3 inch NaI (Tl) scintillation detector. The obtained results indicate that the values of the mass attenuation coefficient (μm), effective atomic number (Zeff) and electron density (Nel) of the glass samples increase with the increasing of WO3. The values of the Poisson's ratio (σ), half value layer (HVL) and Mean free path (MFP) of the investigated glasses were found to decrease with the increasing of WO3 concentration. The μm results have been observed a perfect agreement with the XCOM values for all the glass samples.
