We have studied the energy absorption buildup factors and specific absorbed fraction of energy for the silicon-boron alloys of different composition such as alloy A-Si_0.95-B_0.05, alloy B- Si_0.9-B_0.1, alloy C- Si_0.8-B_0.2, alloy D- Si_0.7-B_0.3, alloy E- Si_0.6-B_0.4 and alloy F- Si_0.5-B_0.5. for wide energy range (0.015–15 MeV) up to the penetration depth of 40 mfp using geometric progression fitting method. Buildup factors increase with the increase in the penetration depth. It has been found that the shielding parameters such as mass attenuation coefficient, effective atomic number and buildup factor values are larger for the silicon-boron alloy Si_0.95-B_0.05 than the other studied silicon-boron alloys. Specific absorbed fraction of energy is maximum for the silicon-boron alloy Si_0.95-B_0.05. Hence, we can conclude that the silicon-boron alloy Si_0.95-B_0.05 is a good absorber of X-rays, gamma and neutrons among the studied alloys. The present study is useful in the field of radiation shielding.

硅硼合金的比吸收能量分数

我们研究了不同成分的硅硼合金的能量吸收累积因子和能量的比吸收率，例如A-Si _0.95 -B _0.05合金，B-Si _0.9 -B _0.1合金，C-Si _0.8 -B合金_0.2，D-Si _0.7- B _0.3合金，E-Si _0.6- B _0.4合金和F-Si _0.5- B _0.5合金_。使用几何级数拟合法可在高达40 mfp的穿透深度范围内获得宽能量范围（0.015–15 MeV）的能量。堆积因子随穿透深度的增加而增加。已经发现，硅硼合金Si _0.95 -B _0.05的屏蔽参数，例如质量衰减系数，有效原子序数和堆积因子值比其他研究的硅硼合金更大。对于硅硼合金Si _0.95 -B _0.05，能量的比吸收率最大_。因此，我们可以得出结论，硅硼合金Si _0.95 -B _0.05是所研究合金中X射线，γ和中子的良好吸收剂。本研究在辐射屏蔽领域是有用的。
