Abstract In this study, gamma ray and neutrons shielding features were evaluated for La+3 co-doped zinc borotellurite glasses with chemical formula {[(TeO2)0.70(B2O3)0.30]0.7(ZnO)0.30}1-x(La2O3)x: 0.01≤ x ≤ 0.05 mol%. Firstly, the mass and linear attenuation coefficients (MAC, LAC) for glasses were calculated via Photon Shielding and Dosimetry (PSD) software (Phy-X/PSD) in the energy range of 0.015–15 MeV. Depending on MAC and LAC, effective shielding parameters: Half value layer and mean free path (HVL, MFP), effective electron density, atomic number, and conductivity (Neff, Zeff, Ceff), exposure and energy absorption buildup factors (EBF, EABF) have been evaluated. In addition, effective fast neutron removal cross section (FNRCS) for the studied glasses have been calculated. The obtained data were compared with those of some commercial glasses and concrete. Results reveal that HVL for all samples can be arranged in the order TBZL1>TBZL2>TBZL3>TBZL4>TBZL5. The HVL, TVL and MFP values of TBZL5 glass are 2.988 cm, 9.927 cm, and 4.311 cm, respectively. TBZL5 glass has the highest Ceff values and TBZL1 glass has the lowest Ceff values. EBF values change range from 1 to 4 at 1 MFP and from 1-1010 at 40 MFP value. Therefore, it can be among the alternative materials that can be preferred in radiation application areas.

La+3共掺杂锌硼硅酸盐玻璃伽马射线衰减特性评估

摘要 本研究评估了化学式为 {[(TeO2)0.70(B2O3)0.30]0.7(ZnO)0.30}1-x(La2O3)x 的 La+3 共掺杂锌硼硅酸盐玻璃的伽马射线和中子屏蔽特性。 :0.01≤x≤0.05mol%。首先,通过光子屏蔽和剂量学 (PSD) 软件 (Phy-X/PSD) 在 0.015-15 MeV 的能量范围内计算玻璃的质量和线性衰减系数 (MAC, LAC)。取决于 MAC 和 LAC,有效屏蔽参数:半值层和平均自由程(HVL、MFP)、有效电子密度、原子序数和电导率(Neff、Zeff、Ceff)、暴露和能量吸收累积因子(EBF、EABF) ) 进行了评估。此外,还计算了所研究玻璃的有效快速中子去除截面(FNRCS)。获得的数据与一些商业玻璃和混凝土的数据进行了比较。结果表明,所有样品的 HVL 可以按照 TBZL1>TBZL2>TBZL3>TBZL4>TBZL5 的顺序排列。TBZL5 玻璃的 HVL、TVL 和 MFP 值分别为 2.988 cm、9.927 cm 和 4.311 cm。TBZL5 玻璃的 Ceff 值最高,TBZL1 玻璃的 Ceff 值最低。EBF 值在 1 MFP 时从 1 到 4 变化,在 40 MFP 值时从 1-1010 变化。因此,它可以成为辐射应用领域首选的替代材料之一。TBZL5 玻璃的 Ceff 值最高,TBZL1 玻璃的 Ceff 值最低。EBF 值在 1 MFP 时从 1 到 4 变化,在 40 MFP 值时从 1-1010 变化。因此,它可以成为辐射应用领域首选的替代材料之一。TBZL5 玻璃的 Ceff 值最高,TBZL1 玻璃的 Ceff 值最低。EBF 值在 1 MFP 时从 1 到 4 变化,在 40 MFP 值时从 1-1010 变化。因此,它可以成为辐射应用领域首选的替代材料之一。
