摘　　要：放射性矿产的勘查及利用过程中不可避免产生废渣,其废渣的放射性含量远高出正常底数值,极个别达正常底数值数十倍以上,这些放射性物源的存在,对当地土壤、水体等环境带来一定的放射性污染。如不及时进行治理,势必将长期对附近环境造成影响,因此探索出一条经济合理的治理方法,对当地环境会起到积极的推动作用,根据上马架子铀矿点的治理特点,采用黄土覆盖的方法对放射性矿产废渣进行治理,起到了非常有效的治理效果,对相似的治理工作起到借鉴作用。It is inevitable to produce waste rock and slag in the process of exploration and utilization of radioactive minerals.The radioactive contents in waste rock and slag that are accumulated on the surface is much higher than the normal value,sometimes more than tens of times higher.The existence of these radioactive sources will bring radioactive hazards to the local surface,farmland,water resource,etc.,and also bring some negative effects to the surrounding natural and ecological environment.The will have long-term negative impacts on the nearby environment if not treated timely.Find an economic and reasonable management method will play a positive role to the government.According to the features of Majiazi uranium ore governance,the study adopts the method of loess cover,to cover the governance of waste residue.The method has good performance and the study provides reference for mines management.
