Gamma-photon and neutron shielding effectiveness of borosilicate glasses with alumina in the chemical structure 40SiO2.10B2O3.xBaO.(45-x)CaO.5Al2O3.yZnO.zMgO glasses: 20≤ x ≤ 40 mol% and y=z=6 wt% were evaluated. The investigated glasses were coded as BCBSA-20B (BaO=20 mol%) to BCBSA-40B (BaO=40 mol%). The results showed that the MAC increased when (BaO) increased in the samples and arranged in order that BCBSA-20B< BCBSA-25B<BCBSA-30B< BCBSA-35B < BCBSA-40B. In terms of MAC values, the BCBSA-40B sample has the lowest values of half-value layer (HVL) and mean free path (MFP), but the highest values of effective atomic numbers (Zeff). Moreover, neutron shielding competences of glasses have been determined via calculating the removal cross section for the fast neutrons ΣR (cm-1) which was highest for BCBSA-40B glass (ΣR = 0.0994 cm-1) among the studied samples. In addition, mass stopping power (Ψ) and the projected range (Φ) for proton and alpha particles also calculated. It is found that BCBSA-40B sample has the lowest Ψ and Φ among the studied glasses. It can be concluded that the replacement of the CaO content with the BaO contents enhances the shielding capacity against the charged particles, electromagnetic radiation, and the fast neutrons. The finding of recent investigations can be useful for advanced nuclear engineering and protection studies.

钡(Ba)增强硼硅酸盐玻璃的核辐射屏蔽能力

化学结构为40SiO2.10B2O3.xBaO。(45-x)CaO.5Al2O3.yZnO.zMgO的氧化铝结构的硼硅酸盐玻璃对γ-光子和中子的屏蔽作用:20≤x≤40mol%,y = z = 6 wt %被评估。将所研究的玻璃编码为BCBSA-20B(BaO = 20mol%)至BCBSA-40B(BaO = 40mol%)。结果表明,当(BaO)增加时,MAC增加,并且以BCBSA-20B <BCBSA-25B <BCBSA-30B <BCBSA-35B <BCBSA-40B的顺序排列。就MAC值而言,BCBSA-40B样本的半值层(HVL)和平均自由程(MFP)最低,但有效原子序数(Zeff)最高。此外,通过计算快中子ΣR(cm-1)的去除截面来确定玻璃的中子屏蔽能力,该中子对于BCBSA-40B玻璃是最高的(ΣR= 0。0994 cm-1)。此外,还计算了质子和α粒子的质量阻止能力(Ψ)和投影范围(Φ)。发现在所研究的玻璃中,BCBSA-40B样品的Ψ和Φ最低。可以得出结论,用BaO含量代替CaO含量可以增强对带电粒子,电磁辐射和快中子的屏蔽能力。最近调查的发现对于先进的核工程和保护研究可能是有用的。可以得出结论,用BaO含量代替CaO含量可以增强对带电粒子,电磁辐射和快中子的屏蔽能力。最近调查的发现对于先进的核工程和保护研究可能是有用的。可以得出结论,用BaO含量代替CaO含量可以增强对带电粒子,电磁辐射和快中子的屏蔽能力。最近调查的发现对于先进的核工程和保护研究可能是有用的。
