| 摘 要： | 东胜地区是当前地浸砂岩型铀矿找矿的热点地区之一,该地区覆盖层较厚,适宜于开展攻深能力较强的氡及其子体方法,本文扼要介绍了210Po法测量原理、工作方法和应用效果。通过对东胜地区地浸砂岩型铀矿探测中的应用研究,得出210Po测量结果形成的曲线在矿体上为低值异常,而在矿体两端呈高值异常。通过U-Ra平衡系数、氡的运移、粒子的反冲、团簇效应等对其进行了解释,说明了该方法应用的有效性。

| Abstract: | The area of DongSheng is one of the focus areas to look for sandstone uranium deposits.The overlay of sandstone type uranium is rather thicker,it is effectual to develop the methods of radon and its daughters with strong deep distinguishing ability,the method of ~(210)Po is one of the method of radon and his daughters.This paper introduces the principle of ~(210)Po and work method.By study the application of exploring sandstone uranium deposits in DongSheng area,draws out the result of low value over the ore body and high value at the verges of the ore body from the ~(210)Po measure curve,by the view of ~(210)Po and the law of Alpha's transporting and moving in the medium,and explaines it by utilizing the dependence of U-Ra equilibrium coefficient,the movement of Radon,the recoil of the Alpha particle,cluster effect and so on.All these showes the validity of the ~(210)Po method. |
