摘要
目前用于地下水中氡浓度观测的仪器,特别是模拟氡观测仪器的更新换代相当缓慢,且普遍采用的FD-105K型静电计和FD-125型氡钍分析器均采用人工鼓泡、读数,存在一定的人为误差。经实验研究认为AlphaGUARD P2000便携测氡仪完全采用自动鼓泡和读数,可避免人工操作带来的误差,提高水氡观测质量,利于捕捉地震异常信息。同时,AlphaGUARAD P2000便携测氡仪携带方便、自带电源、操作简单,可用于野外观测、异常核实和土壤氡的测量,拓展地震地下流体中氡的观测范围。
The technique of monitoring radon concentrations in groundwater has been used for earthquake prediction for nearly half a century.However,the upgrading of radon-monitoring devices has been very slow.Currently,the FD-105 Kelectrometer and FD-125radon-thorium analyzer are the most commonly used devices for measuring radon concentrations in water,but measurement errors may occur because the bubbling process is artificially conducted and the measured data are read by visual observation.This study presents an experimental study of the AlphaGUARD P2000 portable radon monitor,a more advanced device that can automatically perform the bubbling process and read data,avoiding errors caused by manual operation.The improved accuracy of this radon monitor helps to better detect radon anomalies prior to earthquakes.The AlphaGUARD P2000 is portable,battery-powered,and easy to use.It can be used in field observations,verification of anomalies,and measurements of radon concentration in soil for the observation of seismic subsurface fluids.
