A study was conducted to investigate how the addition of WO 3  affects the mechanical, optical, and photon attenuation properties of TeO 2 –Na 2 O glass systems. In this study, four glass systems categorized as W5, W10, W15, and W20 were studied to evaluate the impact of WO 3  on TeO 2 –Na 2 O glass systems in view of the feature of mechanical, optical, and photon attenuation. The rising values of elastic moduli suggest that increasing WO 3  on TeO 2 –Na 2 O glass systems makes the glassy structure more stable. Incorporating WO 3  into TeO 2 –Na 2 O glass systems results in an increased energy band gap, rising from 2.83 to 2.95 eV. This phenomenon, in turn, leads to a decrease in the refractive index, dielectric constant, and optical dielectric constant values from 2.444 to 2.411, 5.975 to 5.811, and 4.975 to 4.811, respectively. While the linear attenuation coefficient (LAC) of the examined glass systems (W5, W10, W15, and W20) displayed a comparable pattern, the LAC value of glass sample W20 stood out as the highest among them. However, due to the addition of WO 3  on the TeO 2 –Na 2 O glass system, at a lower energy region from 0.0284 to 0.06 MeV, there was a little variation among the mass attenuation coefficients of these glass systems studied herein, but a negligible variation was found from 0.662 to 2.51 MeV. The studied glass sample W20 with the highest amount of WO 3  (20 mol%) on the TeO 2 –Na 2 O glass system displayed the lowest half-value layer. However, glass samples W5, W10, and W15 exposed 1.29, 1.07, and 1.03 times higher values of mean free path than W20. In addition, the values of the half-value layer were compared with the literature data of WO 3 –MoO 3 –TeO 2 , BaO–Li 2 O–B 2 O 3 , and CaF 2 –BaO–P 2 O 5  glass systems. Studied glass sample W20 showed the maximum shielding performance from energy 0.284 to 2.51 MeV.
