摘要
介绍了物质对X射线的光电吸收系数和康普顿散射系数的计算方法。作为算例，在约1keV～1MeV的X射线能量范围内，计算了聚四氟乙烯、某双基推进剂和人体鲜骨对X射线的光电吸收系数和康普顿散射系数。
In this paper, the method of calculating X-ray photoelectric absorption coefficient andCompton scatter coefficient for matter is described- As several examples, both the photoelectric absorptionand Compton scatter coefficients of polytetrafluoroethylene, a double-base propellant and human being'sfresh bone, in the X-ray energy range of about 1 keV to l MeV, are calculated.
