天然萤石的放射性元素含量及其影响
The radioactive elements content of natual fluorite and its influence
摘要
Abstract
whether fluorite radioactivity affects human health or not, in view of such a situation, the authors used gamma spectrometer to measure the fluorite radioactivity in different host rocks in five representative fluorite ore districts which are distributed respectively in Zhejiang, Inner Mongolia and Chongqing. The results show that, no matter where the fluorite occurs, i.e., whether it occurs in magmat-ic rocks, metamorphic rocks or sedimentary rocks, the radioactive elements content of fluorite is all by far lower than that of the host rocks. Radioactive elements content of natural fluorite is very low, and the result by using the formula to calculate shows that its radio-active value is much lower than the radioactive limit prescribed by the state. Therefore, except for a small amount of violet black fluorite associated with uranium deposits, the vast majority of natural fluorites cause no harm to human health.关键词
