摘要:
为克服地震测氡仪野外校准氡气固体源监管严格等工作环境问题,引进东华理工大学新研制的豁免级微型氡室开展地震测氡仪野外校准实验,分析该微型氡室应用于地震测氡仪定期校准的可行性。根据《JJG 825-2013测氡仪检定规程》,分别使用微型氡室和标准氡室对2款在网观测测氡仪开展对比校准实验,分析认为采用微型氡室的校准方法基本可行。该微型氡室采用豁免级氡气源及自动化氡浓度控制系统,具备操作便捷、运输方便等特点,适用于地震台站测氡仪的现场定期校准。

Abstract:
In order to overcome the difficulties from strict supervision and other issues of radon standard source in the field calibration of the emanometers,we conducted field calibration experiments of the seismic emanometers with the exempt miniature radon chamber,which is developed by East China University of Science and Technology,and analyzed the feasibility in periodic calibration. In this work,comparative calibration experiments of two emanometers in the network with miniature radon chamber and standard radon chamber were carried out in accordance to JJ825-2013 verification regulation of radon measuring instrument. The results showed that our new method for calibrating the seismic emanometers was basically feasible. The miniature radon chamber adopts exempt radon source and automatic radon concentration control system,and has the characters of convenient operation and transportation that can be used as a regular calibration device in seismic stations to promote the unification of radon observation values of seismic systems.
