In this paper, five barium borate glasses in the chemical composition of $$40\hbox {SiO}_2$$ 40 SiO 2 – $$10\hbox {B}_2\hbox {O}_3$$ 10 B 2 O 3 –xBaO–(45-x)CaO–yZnO–zMgO (where $$x = 0, 10, 20, 30$$ x = 0 , 10 , 20 , 30 , and 35 mol $${y}=z=6\,\hbox { mol}\%$$ y = z = 6 mol % ) have been reported for radiation protection applications. Mass attenuation coefficient ( $$\mu /\rho$$ μ / ρ ) was obtained in the photon energy range of 356 keV–2.51 MeV using PHITS code for the proposed glasses. The $$\mu /\rho$$ μ / ρ values generated by PHITS code were verified by using both of FLUKA code and XCOM program. The $$\mu /\rho$$ μ / ρ values were then applied to derive effective atomic number ( $${Z}_\mathrm{eff}$$ Z eff ), mean free path (MFP), and half value layer (HVL) for all the glasses involved. Additionally, the fast neutron removal cross sections were calculated for each glass. The results reveal that gamma-shielding properties evolve upon adding BaO content in the glasses. It is found that SBC-B35 glass has superior shielding capacity against gamma rays and fast neutrons as compared with different conventional shielding materials and commercial glasses.

用于辐射屏蔽应用的硼酸钡玻璃的研究

本文中五种硼酸钡玻璃的化学成分为$40\hbox {SiO}_2$$ 40 SiO 2 – $$10\hbox {B}_2\hbox {O}_3$$ 10 B 2 O 3 –xBaO –(45-x)CaO–yZnO–zMgO（其中 $$x = 0、10、20、30$$ x = 0、10、20、30 和 35 mol $${y}=z=6\， \hbox { mol}\%$$ y = z = 6 mol % ) 已被报道用于辐射防护应用。质量衰减系数（ $$\mu /\rho$$ μ / ρ ）是在 356 keV–2.51 MeV 的光子能量范围内使用建议的玻璃的 PHITS 代码获得的。通过使用 FLUKA 代码和 XCOM 程序验证 PHITS 代码生成的 $$\mu /\rho$$ μ / ρ 值。然后应用 $$\mu /\rho$$ μ / ρ 值来推导有效原子序数 ( $${Z}_\mathrm{eff}$$ Z eff )、平均自由程 (MFP) 和半值所有涉及的玻璃层（HVL）。此外，计算每种玻璃的快中子去除截面。结果表明，伽马屏蔽性能随着玻璃中 BaO 含量的增加而发展。研究发现，与不同的传统屏蔽材料和商用玻璃相比，SBC-B35 玻璃对伽马射线和快中子的屏蔽能力更强。
