“…At low energies, photoelectric absorption dominated, resulting in a large Z e f f value. The Z e f f values in the current study were compared to other glass samples at 1333 keV that had been published, as seen in Figure 16 [47,48,50,54]. Research results showed the larger value of Z e f f to be more efficient and useful in shielding radiation, as the probability of photon interaction increases with increasing WO 3 concentration, contributing to decreased radiation transmission.…”

The current study aims to enhance the efficiency of lead-free glass as a shielding material against radiation, solve the problem of the dark brown of bismuth glass, and reduce the accumulation of waste glass disposed in landfills by using soda-lime-silica SLS glass waste. The melt-quenching method was utilized to fabricate (WO3)x[(Bi2O3)0.2(ZnO)0.3(B2O3)0.2(SLS)0.3]1−x at 1200 °C, where x= (0, 0.01, 0.02, 0.03, 0.04, and 0.05 mol). Soda lime silica SLS glass waste, which is mostly composed of 74.1 % SiO2, was used to obtain SiO2. Radiation Attenuation parameters were investigated using narrow-beam geometry and X-ray fluorescence (XRF). Furthermore, the parameters related to radiation shielding were calculated. The results showed that when WO3 concentration was increased, the half-value layer was reduced, whereas the μ increased. It could be concluded that WBiBZn-SLS glass is a good shielding material against radiation, nontoxic, and transparent to visible light.
