Abstract

The aim of this study is to evaluate both buildup factors and photon attenuation effectiveness of some borate glasses doped by Cd, Fe, V, and Bi. The mass attenuation coefficients (μ) of these glass systems have been calculated via MCNP6 and GEANT4 computer simulation codes over 0.02-10 MeV energy range and compared with the theoretical results of WinXCOM program. And then, half-value layer, (HVL), mean free path (MFP), and effective atomic number (Z) for the different content based glasses have been determined. Through G-P fitting process, exposure buildup factors (EBF) have been found in the energy range of 0.015-15 MeV up to 40 mfp. It can be concluded that SrBiO20 glass is alternative material in terms of photon attenuation, respectively.

摘要

本研究旨在评估掺 Cd、Fe、V 和 Bi 的几种硼酸盐玻璃的体积累积因子和光子衰减效率。通过 MCNP6 和 GEANT4 计算机模拟代码，计算了这些玻璃系统在 0.02-10 MeV 能区的质量衰减系数(μ)，并与 WinXCOM 程序的理论结果进行了比较。然后，确定了不同含量的半值层（HVL）、平均自由程（MFP）和有效原子序数（Z）。通过 G-P 拟合过程，在 0.015-15 MeV 的能量范围内，发现了 40 mfp 的曝光体积累积因子（EBF）。可以得出结论，SrBiO20 玻璃在光子衰减方面是一种替代材料。
