摘要
为了对比有关土氡观测的稳定性及观测结果的映震能力，在原北川县政府断层气观测场地内建立了三组综合观测孔，进行ＲａＡ法，氡管仪法和α径迹蚀刻法测试实验。同时增加对地面空气中氡含量的测量，以便对比实验效果以确定几种方法的可信度。对连续１７个月三种方法的观测数据进行分析，测试的数据曲线同步性很好，年变规律清楚，观测资料与附近地震发生有较好的对应关系。
To test the stability of observation method of soil radon, three synthetic observation holes were set up in the garden of Beichuan Government. Three methods are RaA, alpha particle track measurement and radon pipe measurement. We tested the amount of radon in the air at same time to compare the results by three methods. After 17 months observation, we find that all the data from each method are same and show the annual change. Some change of data include information of relate to earthquakes.
