氡作为一种寻找隐伏铀矿体的指示元素已应用多年,近几年来,随着铀矿勘探成果的扩大,在氡的探测方法的改进及其测量成果的解释方面获得了许多经验,方法日趋成熟。岩石中产生和释放的氡从矿物晶粒中释放出的氡的量,取决于衰变的Ra的位置、岩石的化学成分和许多其它因素。从岩石中释放的这部分氡,通常被认为是射气系数。其数值范围可以从百分之几到 Radon has been used for many years as an indicator element for finding hidden uranium ore bodies. In recent years, with the expansion of uranium exploration results, many experiences have been gained in the improvement of the detection methods of radon and the interpretation of measurement results, mature. The amount of radon produced and released from rock in the rock from mineral grains depends on the location of the decaying Ra, the chemical composition of the rock, and many other factors. This part of the radon released from the rock is usually considered to be a radiometric coefficient. The value range can range from a few percent
