摘要

计算了天然铀在0.05 ~ 15mev能量范围内，直至穿透深度为40mfp时的能量吸收和暴露积累因子。采用五参数几何级数拟合法计算了铀的富集系数。研究了铀的能量吸收和暴露积累因子随穿透深度和入射光子能量的变化规律。在0.15 MeV时，能量吸收系数和暴露积累系数都很大。

A study of energy absorption and exposure buildup factors in natural uranium

Energy absorption and exposure buildup factor have been computed for natural uranium in the energy range of 0.05-15MeV up to penetration depth of 40 mfp. Five-parameter geometric progression (G-P) fitting method has been used to compute buildup factors of uranium. The variation of energy absorption and exposure buildup factors with, penetration depth and incident photon energies for the uranium has been studied. It has been concluded that the values of energy absorption and exposure buildup factors are very large at 0.15 MeV.
