摘要
锆石是地壳中一种常见的副矿物，又是一种可用作宝石的矿物原料。通过对锆石铀含量变化的研究，探讨了宝石放射性及其对人体是否安全的问题。研究表明，绝大多数天然宝石所含放射性物质是极其微弱的，故不会对人体健康构成危害。对目前一些天然宝石的人工改善品中会残留放射性问题，指出要加强防护监测。
Ziron is a common accessory mineral whlch can be used as material for gem. Studying on variation of uranium content in ziron makes it clear whether gem radioactivity can be safe for human being. The resea-rch result shows most natural gems contain so little radioactive minerals that they can' t he ha-rmful to health. As to residual radioactivity in man-improved gems from nature more protection and inspection should be enhanced.
