Because of the increasing use of phosphate in industry world wide, it is interesting to investigate the elemental concentration in phosphate ores. The present work determines the elemental analysis of two different types of phosphate ores, containing different amounts of P(2)O(5) to check the level of the radioactive elements U and Th and of stable environmental pollutants like Cr, Zn in phosphate raw material. In addition, rare earth and other elements are analysed by the INAA method. This knowledge is found to be important in the assessment of possible radiological hazards to human health, since these materials may be used as building material or as phosphatic fertilizers and animal feed ingredients.
由于全球工业中磷酸盐的使用日益增加，研究磷矿石中的元素浓度很有意思。目前的工作是对两种不同类型的磷矿石进行元素分析，这两种磷矿石含有不同量的P₂O₅，以检测放射性元素U和Th的含量，以及磷矿石原料中稳定的环境污染物如Cr、Zn的含量。此外，采用仪器中子活化分析法（INAA）对稀土元素和其他元素进行分析。发现这些知识对于评估对人类健康可能的放射危害很重要，因为这些材料可能被用作建筑材料、磷肥或动物饲料成分。
