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
錫多金屬礦原礦及圍巖放射性水平受地層與礦化類型影響很大，硫化礦整體放射性水平不高，
砂錫礦卻普遍高出背景值數倍，
尾礦、爐渣放射性水平也相對較高，對環境的影響不容忽視。
