The surface gamma dose was monitored by RS-230 gamma spectrometer in aseismic region from March 2018 to April 2019. The behavior of gamma radiation were analyzed, the results show that is obviously affected by rainfall. Based on the meteorological dataset provided by National Meteorological Information Center, the method for quantitative removal of rainfall interference is proposed. The statistical uncertainty is an intrinsic property of radionuclide and has a significant impact on gamma data. This paper proposed the method to remove statistical uncertainty of gamma radiation based on singular value decomposition and signal-to-noise ratio, which reduced the statistical uncertainty of radiation and preserves the interesting information. The characteristic response of gamma radiation monitoring to seismic activity is analyzed with the data provided by China Earthquake Data Center, and the result showed that the gamma radiation in aseismic region had a certain indication on seismic events.

监测抗震区的伽马辐射及其对地震事件的响应。

利用RS-230伽马能谱仪监测了2018年3月至2019年4月在地震地区的地表伽马剂量。分析了伽马辐射的行为，结果表明降雨明显影响了伽马辐射。基于国家气象信息中心提供的气象数据，提出了定量消除降雨干扰的方法。统计不确定性是放射性核素的固有属性，对伽玛数据有重大影响。提出了一种基于奇异值分解和信噪比的伽玛辐射统计不确定性消除方法，减少了辐射的统计不确定性，保留了有趣的信息。
