摘要为查明滇东南锡多金属矿天然放射性水平，了解锡矿采、选、冶过程中的放射性污染，选择了该区10个锡矿山，测量了各类锡多金属矿原矿、精矿、尾矿及冶炼炉渣放射性核素比活度。 - It is shown that the radioactivity level of tin polymetallic ore , undressed ore and adjacent formation is affected by the strata and mineralization type , the radioactivity level of sulfide ore is not high as a whole , while that of tin ore generally is several times higher than the background value and that of debris and slag is also relatively high , whose impact on the environment is not neglectable
锡多金属矿原矿及围岩放射性水平受地层与矿化类型影响很大，硫化矿整体放射性水平不高，砂锡矿却普遍高出背景值数倍，尾矿、炉渣放射性水平也相对较高，对环境的影响不容忽视。
