摘要
以正在运行的某铀矿山为例,以放射性污染源实际监测数据作为预测源项,采用评价区域的真实地形数据、以最近3年地面气象数据和高空气象数据作为预测条件,利用最新开发的UAIR-FINE软件预测该铀矿山对周围公众的辐射影响。预测结果表明,铀矿冶设施设置辐射防护距离具有一定的局限性。
UAIR-FINE seft was used to predict the radioactive impact of a running uranium mine to local residents.Monitoring data of radioactive pollution source was used as source terms,and regional terrain data,ground and upper air meteorological data of last three years were used as prediction condition.The prediction results indicates that the practice of setting radioactive protection distance around uranium mining and metallurgy facilities has certain limitations.
