山西夏县中心地震台断层逸出气氡、溶解水氡测值干扰因素分析

Analysis of Interference Factors of Values of Radon Gas Escaped from Fault and Radon Dissolved in Water at Xiaxian Central Seismological Station,Shanxi

山西夏县中心震台断层逸出气氡及溶解水氡分别观测中条山山前断裂土壤逸出气氡及热水井的水中溶解氡值。观测灵敏度高、信息量大,但易受其他因素的干扰。通过对观测值进行分析,发现,夏县台断层逸出气氡测值与气温呈正相关,与气压呈负相关;气温、气压对夏县台热水井溶解水氡测值几乎没有影响,但受水位的影响较明显。

Radon gas escaped from soil and radon dissolved in thermal well are measured around the Zhongtiaoshan piedmont fault by Xiaxian Central Seismological Station .The observations have high sensitivity and contain large amount of information , but are easily interfered by oth-er factors.By analyzing the observation values , it is concluded that the radon gas escaped from fault is positively correlated to air temperature and negatively correlated to barometric pressure .The temperature and pressure almost have no any influence on the value of radon dissolved in water of thermal well at Xiaxian station , mean while the water level has obvious impact on it instead .
