美国放射性污染场址整治中土壤的清洁水平

Soil Cleanup Levels in Remedying Radioactively Contaminated Sites in America

简要介绍了美国污染场址整治中确定土壤清洁水平的开发过程,给出了某些场址的清洁水平,并对其进行了比较。由于多种因素影响,不同场址的清洁水平是不同的,即使是同一场址,不同评价方法导出的清洁水平也不同。因此,一个场址的清洁水平不能简单地用于其它场址。

Development process of soil cleanup levels in remedying radioactively contaminated sites in America is brief introduced, Some soil cleanup level values are given and the values are compared in this paper. It is concluded from analysis of the results that cleanup levels from site to site are different because of variations in one or more of the elements in the cleanup level development process, and the cleanup levels derived from different assessment approaches are different even at the same site. Cleanup levels, therefore, used at one site should not be simply used at other sites.
