摘　　要：总结了2个铀矿冶退役治理过程中污染场地清挖工程量增大的情况。以退役治理工作中清挖治理量超出设计量较多的具体实例,说明了源项对铀矿冶退役治理工程的重大影响。通过进一步的分析,找出了影响源项变化的原因。提出了在退役治理工作中改进源项调查方法的建议:1)加密采样点;2)采用探槽法取样;3)详细调查生产期间的资料;4)检查物料平衡;5)施工中补充完善源项调查。Two uranium mines decommission projects were found out engineering work quantities in- creased in the cleaning and digging the pollutant area. Taking the concrete decommission projects as examples, it is pointed out source terms which have great important effect in the uranium mine decom- mission engineering process. The reasons for source terms change were found out by the further anal- ysis. Five point suggestions for improving source term investigation was made as the following： 1） compacting sampling site, 2） using deep groove sampling method, 3） minutely investigating data and information in production period, 4） checking out mass balance, 5） supplementing source term inves- tigation under construction engineering project.
