核设施退役后土壤中容许剩余放射性水平和其他一些标准

DETERMINATION OF ALLOWABLE RESIDUAL RADIOA-CTIVITY LEVELS IN SOIL FOLLOWING DECOMMISSIONING

对污染土壤的处置，是核设施退役过程中最重要的补救措施之一；土壤中的剩余放射性又构成了退役后对公众产生直接和经常照射的主要源项。因此对退役场址土壤中容许剩余放射性水平（ＡＲＣＬ）的确定是核设施退役中最受关注的一个问题。本文在考虑到我国退役工作需要的基础上，着重介绍了国际上对ＡＲＣＬ的确定方法及其有关因素的考虑。

Residual radioactivity in soil is the main source of exposure to the public after decommissioning of nuclear site.Determining allowable residual radioactivity levels(ARCL)insoil is one of commonly concerned problems for decommissioning nuclear site. This paper in-troduces methods for determining ARCL in soil and related consideration of important factors.
