Development of Novel Transparent Radiation Shielding Glasses by BaO Doping in Waste Soda Lime Silica (SLS) Glass

Abstract

In the current study, BaO was doped in Bi2O3-ZnO-B2O3-SLS glass to develop lead-free radiation shielding glasses and to solve the dark brown of bismuth glass. The melt-quenching method was utilized to fabricate (x) BaO (1 − x)[0.3 ZnO 0.2 Bi2O3 0.2 B2O3 0.3 SLS] (where x are 0.01, 0.02, 0.03, 0.04, and 0.05 mol) at 1200 °C. Soda lime silica glass waste (SLS), which is mostly composed of 74.1% SiO2, was used to obtain SiO2. The mass attenuation coefficient (μm) was investigated utilizing X-ray fluorescence (XRF) at 16.61, 17.74, 21.17, and 25.27 keV and narrow beam geometry at 59.54, 662, and 1333 keV. Moreover, the other parameters related to gamma ray shielding properties such as half-value layer (HVL), mean free path (MFP), and effective atomic number (Zeff) were computed depending on μm values. The results indicated that HVL and MFP decreased, whereas μm increased with an increase in BaO concentration. According to these results, it can be concluded that BaO doped in Bi2O3-ZnO-B2O3-SLS glass is a nontoxic, transparent to visible light, and a good shielding material against radiation.

Insights into the Effect of Aggregate Sizes on the Soil Radiation Interaction Properties Based on X-ray Fluorescence

“…The decreased Z eff in the energy region from ~10 −2 to ~10 −1 MeV is explained by changes in the dominance of the effects responsible for the photon absorption and scattering [ 17 , 20 ]. Similar findings were also found in studies with gemstones [ 45 ], granite [ 46 ], clay [ 47 ], and glasses [ 40 , 48 ].…”

“…For N el ( Figure 3 c,d and Figure 5 c,d), our results are directly associated with the relation between this nuclear parameter and Z eff (Equation (5)) [ 19 , 25 , 49 ]. The curve decays observed from ~10 −2 to ~10 −1 MeV are also explained by partial effect dominance changes in the photon absorption and scattering [ 48 ]. For c. 60 keV ( Tables S4 and S5—Supplementary Materials ), N el presented an inverse relation with Fe 2 O 3 , μ/ρ, σ A , and σ E , explaining the curve inversions compared to Z eff .…”

Concentration dependence of visible luminescence from Pr3+-doped niobium zinc barium boro-tellurite glasses

“…Zinc oxide (ZnO) enhances the capacity of borotellurite glass to construct glass matrices and reduce crystallization rates [1]. Barium oxide (BaO) is known for its high resistance to extreme radioactive radiation, increased density, and enhanced optical transparency [2]. Niobium oxide (Nb2O5) is chosen due to its vacant d-orbital, known for strengthening nonlinear optical sensitivity [3].…”
