| 摘 要： | 文章对比分析研究了江西相山铀矿区和非铀矿区稻谷中天然放射性核素U和Th的含量特征。样品分别采自江西省相山铀矿区及远离铀矿区的抚州市郊丘陵水稻种植区。结果表明相山铀矿区稻谷中天然放射性核素U的含量显著高于非铀矿区的稻谷，铀矿区内稻谷中放射性核素U含量平均值是非铀矿区的5.30倍;但铀矿区内稻谷中放射性核素Th的含量却较非铀矿区稻谷含量低，仅为其Th含量的50%。另外，相山铀矿区内稻谷中放射性核素U和Th之间存在较为显著的线性关系，稻谷中放射性核素Th的含量随U含量的增加而升高。铀矿区内稻谷中放射性核素U含量显著高于非铀矿区的原因还有待于进一步深入研究，然而加强该领域的研究对于保证我国区域稻谷质量和食品安全是非常重要和有意义的。

| Abstract: | The contents of natural radioactive nuclides such as uranium and thorium in paddies were analyzed and compared by means of ICPMS.Totally 14 paddy samples were distinguished into two groups and collected from two rice planting area.One group(12 paddy samples) was collected from the Xiangshan uranium deposit area,Jiangxi province;while the other group(2 samples) collected from non-uranium deposit suburban area of Fuzhou city,Jiangxi,as comparison samples.The distance between the two sampling areas is about 80... |
