摘　　要：根据层间氧化带型砂岩铀矿的矿化富集与铀镭平衡变化特征，在西北层间氧化带型砂岩铀矿床运用地面放射性氡法———２１８Ｐｏ 测量方法进行了找矿试验，试验表明运用２１８Ｐｏ 测量结果曲线来圈定层间氧化带中铀矿化富集部位是可行和有效的。Based on mineralization enrichment and uranium radium equilibrium variation characteristics of interstratified oxidized zone type sandstone uranium deposits,the authors used surface radioactive radon technique,namely 218 Po measurement technique,to make ore prospecting test in this type of uranium deposits within Northwest China.The results show that the utilization of curves obtained from 218 Po measurement to the delineation of uranium mineralization enrichment position within the interstratified oxidized zone is feasible and effective.
