~(222)Rn 衰变能产生一系列短寿命的衰变产物,这些衰变产物能附着于平板或金属丝的表面上。用简单的计数方法能够测量衰变产物~(218)Po 和~(214)Po 的α放射性。这种现象有可能用于直接找铀。实验室的研究表明:1.氡的衰变产物能被收集在各种材料上(包括各种金属和塑料),2.α强度的增高与收集器的表面积大小有关;3.用加负电压的方法可以增强收集作用。用这种新方法在南马奇铀-铜矿点上圈出异常。还研究了一种用于测量土壤样品中镭的方法。对两种研究结果与常规方法获得的结果进行了比较。
~ (222) Rn decay can produce a series of short-lived decay products that attach to the surface of plates or wires. The α radioactivity of decay products ~ (218) Po and ~ (214) Po can be measured by simple counting method. This phenomenon may be used to find uranium directly. Laboratory studies have shown that: 1 radon decay products can be collected in a variety of materials (including a variety of metals and plastics), 2.α increase in the strength of the collector surface area size; 3 with a negative voltage The method can enhance the collection effect. Using this new method, anomalies are circled at the South Mud Uranium-Copper Deposit. A method for measuring radium in soil samples has also been studied. The results of the two studies were compared with those obtained by the conventional method.
