AlphaGUARD P2000便携测氡仪野外观测影响因素探讨
Experimental Investigation on Influence Factors on the Field Observations of the AlphaGUARD P2000 Portable Radon Monitor

使用AlphaGUARD P2000便携测氡仪对土壤氡浓度观测的采气条件、影响因素等进行了测量实验研究，探讨土壤氡的测定方法，试图找出影响土壤氡测定结果准确性相关因素，为制定有效测定方法提供依据。
As a radioactive gas geochemical survey method, soil radon measurement can be affected by a lot of interference. If we do not pay attention to these interference factors while testing, interference and abnormal phenomena will be observed; these present great difficulties while analyzing the data. The P2000 is portable, battery-powered, and easily operable. It can be used for field observation, anomaly verification, and the measurement of soil radon concentration for seismic subsurface fluid observation. In this study, based on soil radon concentration measurements using the AlphaGUARD P2000 portable radon monitor, we analyze the gas recovery conditions and influencing factors, discuss the soil radon determination method, and try to identify related factors that influence soil radon measurement.
