摘要: 根据氡观测仪的氡室校准和氡气固体源校准两种校准方式的实验结果, 讨论了使用标准仪器校准氡观测仪器的可靠性问题。 用国际公认的计量传递仪器AlphaGUARD P2000Pro或AlphaGUARD P2000F测氡仪作为氡气溯源仪器, 对九江地震台FD-125氡钍分析器的三个闪烁室进行了氡室校准、 氡气固体源校准和仪器校准三种方法实验, 得到标准仪器校准、 氡气固体源校准得出K值相对氡室校准结果偏差均小于6%, 结果表明, 三种方法的校准结果均符合目前氡观测计量溯源技术要求, 能达到与国家氡计量刻度相统一目的。

Abstract: In this paper, the reliability of calibrating radon observation instruments using standard instruments is verified on the experimental results of radon chamber calibration and solid radon source calibration. The AlphaGUARD P2000Pro and AlphaGUARD P2000F radon measuring instrument of German Genitron Company, the classic measuring and transmitting instrument of radon measurement laboratory, are used as the source traceability instrument for the transmission source. The observation of water radon in Jiujiang Seismological Station FD-125 radon thorium chamber is calibrated by three calibration methods, including radon chamber calibration, solid radon source calibration and instrument calibration. The calibration of standard instruments and calibration of solid radon gas sources indicates that the deviation of the K value relative to the radon chamber calibration results is less than 6%, and they can meet the needs of the current radon observation and measurement. It can achieve the goal of unification with the national radon calibration scale.

Key words: Radon observation, Radon solid source calibration, Radon chamber calibration, Alpha GUARD measuring system
