Some Questions Related to Radionuclide Shore/Beach Sediment Models

摘要: 文章涉及目前国际上使用的两种放射性核素岸滩沉积模式，NRC岸滩沉积评价模式和IAEA岸滩评价模式，指出了这两个模式中存在的某些问题，并基于用射线的线衰减系数的倒数μ^－1值代替沉积物的有效沉积厚度d，提出了一种推荐模式。此外，对合理选择评价模式参数提出了建议。

Abstract: The paper concerns in the two kinds of radionuclide shore/beach sediment models at present, NRC and IAEA shore/beach sediment models. Some existent questions in the two models are pointed, and a recommendable model is put forward, in which the thickness of sediment layer is replaced by the reciprocal of attenuation coefficient 1/μ. In addition, some recomendations on model parameters choice are given in the paper.
