山西水氡观测K值标定误差及原因分析

Calibration Error and Cause Analysis of K Value in Water Radon Observation in Shanxi Province

仪器K值标定规范了地震地下流体的监测工作,使所有数据可以相比或者归一,对地震地下流体预报分析具有积极作用。文章以山西定襄台水氡观测为例,探讨仪器K值标定过程中需要注意的问题,运用实验数据分析K值标定误差及其原因,并提出减少闪烁室K值标定误差的一些建议。

The K-value calibration of instruments regulates the monitoring of seismic underground fluid,makes all data compared or normalized,and plays an active role in the prediction and analysis of seismic underground fluid.Taking the water radon observation at Dingxiang station in Shanxi Province as an example,this paper discusses the problems needing attention in the calibration process of instrument K-value,analyses the calibration error of K-value with experimental data and its causes,and puts forward some suggestions to reduce the calibration error of scintillation chamber K-value.
