Abstract

In this study, photon interaction parameters such as radiation protection efficiency (RPE), total mass attenuation coefficient (μ/ρ), linear attenuation coefficients (μ), half value layers (HVL), tenth value layers (TVL), mean free paths (MFP), effective atomic numbers (Z_Eff) and effective electron densities (N_Eff) were experimentally investigated for the BCZrB-0, BCZrB-10, BCZrB-20, BCZrB-30, BCZrB-40 and BCZrB-50 in the energy range from 59.5 keV to 1332.5 keV. In the experiment, HPGe detector and ²⁴¹Am (59.5 keV), ¹³³Ba (81 keV, 276.4 keV, 302.9 keV, 356 keV and 383.9 keV), ²²Na (511 keV and 1274.5 keV), ¹³⁷Cs (661.7 keV), and ⁶⁰Co (1173.2 keV and 1332.5 keV) radioactive point sources were used. Experimental results compared with results of the WinXCOM, GEANT4 simulation code and FLUKA simulation code. Energy absorption build-up factors (EABF) and exposure build-up factors (EBF) were calculated with G-P fitting method in the energy region 0.015 MeV ≤ E ≤ 15 MeV. Kerma relative to air values were investigated in the energy region 0.001 MeV ≤ E ≤ 20 MeV. Effective removal cross section, total macroscopic cross section and number of transmitted neutron values were defined for composites. The agreement between experimental and WinXCOM program, between experimental and GEANT 4 simulation codes and between experimental and FLUKA simulation codes of gamma-ray interaction parameters are < 5.1%, < 6.5% and < 5%, respectively. All of the results are compatible with each other and BCZrB-50 is a good gamma-ray radiation absorber in the studied composites and BCZrB-0 is the best neutron absorber in the studied composites.

碳化硼/硼化锆复合材料辐射相互作用参数研究

在59.5 ~ 1332.5 keV能量范围内，对BCZrB-0、BCZrB-10、BCZrB-20、BCZrB-30、BCZrB-40和BCZrB-50的辐射防护效率（RPE）、总质量衰减系数（μ/ρ）、线性衰减系数（μ）、半值层（HVL）、十值层（TVL）、平均自由程（MFP）、有效原子序数（ZEff）和有效电子密度（NEff）等光子相互作用参数进行了实验研究。实验采用HPGe探测器和241Am （59.5 keV）、133Ba （81 keV、276.4 keV、302.9 keV、356 keV和383.9 keV）、22Na （511 keV和1274.5 keV）、137Cs （661.7 keV）和60Co （1173.2 keV和1332.5 keV）放射性点源。实验结果与WinXCOM、GEANT4仿真代码和FLUKA仿真代码的结果进行了比较。在0.015 MeV≤E≤15 MeV的能量区，用G-P拟合法计算能量吸收累积因子（EABF）和暴露累积因子（EBF）。在0.001 MeV≤E≤20 MeV的能量范围内，研究了相对于空气的Kerma值。定义了复合材料的有效去除截面、宏观总截面和透射中子数。伽玛射线相互作用参数实验码与WinXCOM程序、实验码与geant4仿真码、实验码与FLUKA仿真码的一致性分别为5.1%、6.5%和5%。结果一致，BCZrB-50是所研究复合材料中较好的γ射线吸收剂，BCZrB-0是所研究复合材料中较好的中子吸收剂。
