在金矿勘查中,金矿中氡源是进行氡气测量的前提条件。含矿构造破碎带有利于氡气扩散迁移。构造中含有弱承压水或含水,覆盖层疏松且厚度不是很大,是进行壤中氡测量的必备条件。雨水对壤中氡气测量影响很大,降低氡的浓度,异常幅度很低,野外工作应避开雨天大雨后,在第三天进行测量效果最佳。本方法具快速、经济、有效。
In the gold exploration, gold sources in radon is a prerequisite for radon measurement. Containing structure broken zone is conducive to the proliferation of radon migration. The structure contains weak confined water or water, the cover is loose and the thickness is not very large, is the necessary conditions for soil radon measurements. Rain on the soil radon measurement great impact, reduce the concentration of radon, the anomaly range is low, the field work should be to avoid rain after the rain, the best measurement on the third day. The method is fast, economical and effective.
