In this study, a group of heavy metal oxide glasses with a nominal composition of 55BO + 19.5TeO + 10KO + (15-x) PbO + xAlO + 0.5EuO (where x = 0, 2.5, 5, 7.5, 10, 12.5, and 15 in wt.%) were investigated in terms of their nuclear radiation shielding properties. These glasses containing lanthanide-doped heavy metal oxide were envisioned to yield valuable results in respect to radiation shielding, and thus a detailed investigation was carried out; the obtained results were compared with traditional and new generation shields. Advanced simulation and theoretical methods have been utilized in a wide range of energy regions. Our results showed that the AL0.0 sample with the highest PbO contribution had superior shielding properties in the entire energy range. The effective removal of cross-sections for fast neutrons (Σ) was also examined. The results indicated that AL5.0 had the greatest value. While increasing the concentration of AlO in samples had a negative effect on the radiation shielding characteristics, it can be concluded that using PbO in the Eu doped heavy metal oxide glasses could be a useful tool to keep gamma-ray shielding properties at a maximum level.
在本研究中,研究了一组标称组成为55BO + 19.5TeO + 10KO + (15 - x)PbO + xAlO + 0.5EuO(其中x = 0、2.5、5、7.5、10、12.5和15,单位为重量百分比)的重金属氧化物玻璃的核辐射屏蔽性能。这些含有镧系元素掺杂的重金属氧化物的玻璃有望在辐射屏蔽方面产生有价值的结果,因此进行了详细研究;将所得结果与传统屏蔽材料和新一代屏蔽材料进行了比较。在广泛的能量区域中使用了先进的模拟和理论方法。我们的结果表明,PbO含量最高的AL0.0样品在整个能量范围内具有优异的屏蔽性能。还研究了快中子的有效去除截面(Σ)。结果表明AL5.0的值最大。虽然增加样品中AlO的浓度对辐射屏蔽特性有负面影响,但可以得出结论,在掺铕重金属氧化物玻璃中使用PbO可能是将伽马射线屏蔽性能保持在最高水平的有用手段。
