摘要
分析了砂岩型铀矿床上氡及其子体异常特征及其形成的机理,介绍了砂岩型铀矿床上氡及其子体经α衰变后产生的α粒子的反冲现象、团簇理论和自然电场,分析了砂岩铀矿床的地质特点、U-Ra平衡、磁化率、自然电位的变化等,对砂岩铀矿勘查的氡及其子体异常解释有一定的指导意义。
This paper has studied the characteristics and formation mechanism of the anomalies caused by radon and its daughters over the sandstone uranium deposit, described the recoil of the Alpha particles, the cluster effect and the natural electric field over the sandstone uranium deposit, and analyzed geological characteristics of the sandstone uranium deposit. The U-Ra balance, the magnetic susceptibility, and the change of the natural voltage are also discussed. The results obtained are of instructive significance in explaining the anomalies of radon and its daughters over the sandstone uranium deposit.
