针对P2000与RAD7型测氡仪相同测量条件下氡浓度测值存在差异的现象,在张家口渤海地震带野外进行断层气体氡测量对比实验。实验结果表明,钍射气是造成两台测氡仪观测值差异的主要原因。根据钍射气及其子体衰变期,先使用气袋采集断层气体,静置5~10min后再进行测量,较好的解决了氡浓度测值差异较大的现象。通过断层气体氡的野外测量方法,为两种仪器观测值直接对比提供了可能,也为地震监测技术方法改进提供参考。
- 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.
