摘要
以中国首家中性原地浸出采铀企业为研究对象,对原地浸出采铀的辐射环境影响进行了分析与评价。评价表明,地浸采铀对周边环境和公众的影响很小。但是,由于采场可能与当地的农田或牧场相重合,在评价中,除一般需考虑的因素外,还应对当地居民的活动行为和生活方式进行调查并合理确定相关评价参数。同时,建议尽可能将浸出液集液过程密封处理,降低集液过程溶解氡气的释放,进一步降低地浸采铀可能的辐射环境影响。
Taking the first uranium mining enterprise by neutral(CO2+O2)in-situ leaching process in China as the research object,the radiation environmental impact of in-situ leaching uranium mining was evaluated,and the results were analyzed further.It shows that the impact of in-situ leaching on the surrounding environment and the public is very small.However,as the stope of in-situ leaching may overlap with the local farmland or pasture,in addition to the general factors to be considered,the activities and lifestyle of local residents should be investigated and the relevant evaluation parameters should be reasonably determined.At the same time,it is suggested that the leaching solution collection process should be sealed as much as possible in the process of in-situ leaching,so as to reduce the release of dissolved radon and further reduce the possible radiation environmental impact of in-situ leaching.
