Radiation parameterizations and optical characterizations for glass shielding composed of SLS waste glass and lead-free materials

The novelty in the present search, the Soda-Lime-Silica (SLS) glass waste to prepare free lead glass shielding was used in order to limit the accumulation of glass waste, which requires extensive time to decompose. This also saves on the consumption of pure SiO2, which is a finite resource. Furthermore, the combining of BaO with Bi2O3 into a glass network leads to increased optical properties and improved attenuation. The UV-Visible Spectrophotometer was used to investigate the optical properties and the radiation shielding properties were reported for current glass samples utilizing the PhysX/PDS online software. The optical property results indicate that when BaO content increases in glass structure, the Urbach energy DE, and refractive index n increases while the energy optical band gap Eopt decreases. The result of the metallisation criteria (M) revealed that the present glass samples are nonmetallic (in-sulators). Furthermore, the radiation shielding parameter findings suggest that when BaO was increased in the glass structure, the linear attenuation coefficient and effective atomic number (Zeff) rose. But the half-value layer HVL declined as the BaO concentration grew. According to the research, the glass samples are non-toxic, transparent to visible light, and efficient radiation shielding materials. The Ba5 sample is considered the best among all the samples due to its higher attenuation value and lower HVL and MFP values, which make it a suitable candidate as transparent glass shield shielding.(c) 2022 Korean Nuclear Society, Published by Elsevier Korea LLC.

Automated summary

The present study focuses on using Soda-Lime-Silica (SLS) glass waste to prepare lead-free glass shielding materials to reduce the accumulation of glass waste and conserve SiO2 resources. By adding BaO and Bi2O3 to the glass structure, the optical and attenuation properties of the glass are improved. The results show that increasing the BaO content in the glass structure enhances the linear attenuation coefficient and effective atomic number, while decreasing the half-value layer. The glass samples are proven to be non-toxic, transparent, and efficient radiation shielding materials.
