Abstract

This work investigates the impact of BaO, PbO2, and Gd2O3 on newly developed borate glasses’ radiation shielding characteristics. The transmission factor (TF) of the glasses is almost zero at the low energy of 0.0395 MeV, which indicates favorable low-energy photon shielding. The maximum TF is reported at 1.46 MeV for the free Gd2O3 glass sample, ranging from 0.89 (0.5 cm thickness) to 0.73 (1.5 cm thickness). Moreover, with more BaO, PbO2, and Gd2O3 content added to the glasses, the TF decreases, indicating an enhancement in the efficiency of the glasses’ radiation protection with the introduction of BaO, PbO2, and Gd2O3. There is a 4.309 to 5.068 g cm−3 increase in the glasses’ density, and, as a result, the mean free path decreases, suggesting improved performance for radiation protection with the adding of more BaO, PbO2, and Gd2O3 contents to the glasses. At 0.122 MeV, the free Gd2O3 glass’s half value layer value is 0.098 cm, while the tenth value layer is 0.325 cm.

多组分玻璃的辐射屏蔽分析：不同 BaO、PbO2 和 Gd2O3 浓度的影响

这项研究探讨了 BaO、PbO2 和 Gd2O3 对新开发的硼酸盐玻璃辐射屏蔽特性的影响。在 0.0395 MeV 的低能量下，玻璃的透射系数（TF）几乎为零，这表明玻璃具有良好的低能量光子屏蔽性能。游离 Gd2O3 玻璃样品在 1.46 MeV 时的透射系数最大，从 0.89（0.5 厘米厚）到 0.73（1.5 厘米厚）不等。此外，随着玻璃中加入更多的 BaO、PbO2 和 Gd2O3，TF 值会降低，这表明随着 BaO、PbO2 和 Gd2O3 的加入，玻璃的辐射防护效率会提高。玻璃的密度增加了 4.309 至 5.068 g cm-3，平均自由路径也随之减小，这表明随着玻璃中 BaO、PbO2 和 Gd2O3 含量的增加，玻璃的辐射防护性能也有所提高。在 0.122 MeV 时，游离 Gd2O3 玻璃的半值层值为 0.098 厘米，而十值层值为 0.325 厘米。
