In this study, the albedo factors (number, energy, and dose) of some boron compounds were investigated at a scattering angle of 180°. Eight boron compounds were tested in the mean atomic number range of 4.571 ≤ $\bar{Z}$ ≤ 19.00. The samples were irradiated by gamma rays emitted at 59.54 keV from an Am-241-point source with an activity of 0.43 MBq. The scattered gamma rays were counted by an ultra-low energy germanium detector with a resolution of 140 eV at 5.9 keV. The results showed that the albedo factors decreased as the mean atomic number increased. The correlations between the albedo factors and mean atomic numbers were also high.

一些硼化合物在59.54 keV处的反照率因子

在这项研究中，研究了一些硼化合物在180°散射角下的反照率因子（数量，能量和剂量）。测试了八种硼化合物，其平均原子序数范围为4.571≤$\stackrel{〜}{ž}$≤19.00。从59.54 keV的Am-241点光源以0.43 MBq的活度发射的伽玛射线辐照样品。散射的伽马射线由超低能量锗探测器以5.9 keV的分辨率对140 eV进行计数。结果表明，反照率随平均原子序数的增加而减小。反照率因子与平均原子序数之间的相关性也很高。
