摘要
计算了各种海洋沉积物的γ射线质量衰减系数．结果表明在１５０ｋｅＶ～１０ＭｅＶ能区，不同沉积物的γ射线质量衰减系数相差甚微，但在小于１００ｋｅＶ能区，差异明显，即使是同一类沉积物，当其元素含量差异较大时，μρ也有显著的不同．海洋沉积物μρ实测值与计算值的比较表明。
The γ ray mass attenuation coefficients of several marine sediments were calculated .The results show that there is no apparence difference in the energy range of 150 keV￣10 MeV, but significant difference appears in the energy range of 10￣100 keV not only among various sediments but also among the same kind of sediment with different chemical compositions. The comparison of μ ρ of the marine sediment indicates that the values measured and calculated are coincident within errors.
