用于野外土壤氡定期定点观测的方法探究
|
摘要
在防震减灾工作对地震监测预报能力的要求不断提高的情况下,氡因其在地震孕育过程中灵敏的前兆响应能力,应该得到更广泛的推广和应用。但由于地下水资源的过度开采,水氡观测环境日益恶化,而目前持续的土壤氡定点观测又相对较少,为此,本文通过选取已知断层,使用AlphaGUARD P2000测氡仪,分别从测量位置、测量周期、集气装置3个方面总结了一种用于野外流动测量土壤氡的定点观测方法,为土壤氡观测在活动断层监测、异常核实中的应用提供参考。
With the increasing demand for earthquake monitoring and prediction in the new era,observation of radon should be widely popularized and applied because of its sensitive response in seismology. However,due to the excessive exploitation of groundwater resources,the observation environment of water radon is deteriorating and the long-standing observation of soil radon is relatively rare at present. For this reason,using the AlphaGUARD P2000 radon meter observation results of a known fault for more than one year's measurements,this paper proposes a periodical fixed-point observation method of soil radon in the field in aspects of the measurement position,the measurement period and the gas gathering device respectively. It provides a reference for the application of soil radon observation in the monitoring of active fault and the application of abnormal verification.
