摘要
Abstract
In view of the phenomenon of difference in radon concentration measured by P2000 and RAD7 radon detectors under the same measuring conditions,a comparative experiment of fault gas radon measurement was carried out in the field of Zhangjiakou Bohai seismic zone.The experimental results show that thorium emanation is the main reason for the difference between the two radon detectors.According to the decay period of thorium emanation and its daughters,this paper firstly collects fault gas with an air bag,and then measures it after standing for 5 to 10 min,which better solves the phenomenon of large difference in measured radon concentration.Through the field measurement method of fault gas radon,it is possible to directly compare the observed values of the two instruments,and also provides a reference for the improvement of seismic monitoring technology.关键词
