Abstract In this study, WO 3 based glass system in composition (100- x )[0.1B 2 O 3 -0.4P 2 O 5 -0.5PbO]- x WO 3 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 (μ m ), effective atomic number (Z eff ) and electron density (N el ) of the glass samples increase with the increasing of WO 3 . 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 WO 3 concentration. The μ m results have been observed a perfect agreement with the XCOM values for all the glass samples.
