摘　　要：目前,在我国铀矿勘查领域中,利用钋、氡等放射性子体特征来勘查、寻找铀矿是较为普遍的一种方式,例如:伽玛能谱测量、放射性气体测量、土壤氡测量等。其中,在岩体表面或地表浅部,主要采用地面伽玛能谱测量的方式,直接寻找铀异常或铀矿化线索;随着勘查深度的增加,主要采用氡及其子体测量方法探寻与铀成矿相关的信息。其中,RaA法作为一种直接、快速、效果明显的氡气测量方法,近年来,在我国铀矿勘查领域中应用日益广泛。文章综合介绍了RaA法测氡的工作原理,并通过采用HDC型测氡仪在两个不同地区进行RaA法测氡的实例效果,说明该方法在目前我国铀矿勘查中的有效性和适用性。At present,in the field of uranium exploration in China,it is a more common way to find uranium ore by using radioactive daughters such as strontium and barium.For example:gamma spectroscopy,radioactive gas measurement,soil enthalpy measurement,etc.Among them,on the surface of rock mass or shallow surface,the ground gamma ray spectrum measurement method is mainly used to directly search for uranium anomalies or uranium mineralization clues.With the increase of exploration depth,the detection methods of strontium and its daughters are mainly used.Information related to uranium mineralization.Among them,the RaA method is a direct,rapid and effective helium measurement method.In recent years,it has been widely used in the field of uranium exploration in China.This paper comprehensively introduces the working principle of RaA method to measure enthalpy,and uses the HDC type sputum instrument to carry out the RaA method in two different regions.The effectiveness and applicability of this method in the current uranium exploration in China is illustrated.
