摘要
研究了 CeO2 对 SiO2-B2O3-BaO-Li2O 玻璃辐射屏蔽性能的示范影响。观察到密度 ρ 的变化趋势在 3.127 至 4.022 g/cm³ 之间,而这些玻璃的摩尔体积 V m 则有所下降。CL玻璃的半值层(HVL)和平均自由路径(MFP)强化了这样一种观点,即铈离子的存在,尤其是在CL2中,增强了玻璃衰减伽马射线的能力。有效电子密度(N eff)随着二氧化 Ce 的加入而增加,这表明辐射屏蔽性能的增强与玻璃中二氧化 Ce 的加入量之间存在相关性。
Gamma and neutron attenuation of SiO2–B2O3–BaO–Li2O glasses doped with CeO2
The demonstrations impact of CeO2 on the radiation shielding properties of SiO2–B2O3–BaO–Li2O glasses has been investigated. The observed trend in density ρ ranged from 3.127 to 4.022 g/cm³, whereas the molar volume Vm of these glasses decreased. The half-value layers (HVL), and mean free paths (MFP) of CL glasses reinforce the notion that the presence of Ce ions, particularly in CL2, enhances the ability of glasses’ to attenuate gamma rays. The effective electron density (Neff) increases with the addition of CeO2, suggesting a correlation between the enhancement of radiation shielding properties and the amount of CeO2 incorporated into the glasses.
