|
Abstract:
根据目前地震系统测氡仪校准和校准周期内的期间核查的需要，本文采用HD-min微型氡室对地震氡观测仪器检测平台在线比测的BG2015-R闪烁室测氡仪进行校准实验，依据JJG825-2013《测氡仪检定规程》的相关技术要求，选取浓度为3000 Bq/m3进行效能校准测试，实验表明用该HD-min微型氡室校准在线比测的BG2015-R闪烁室测氡仪是可行的。该HD-min微型氡室系统可以摆脱镭源的监管限制，能够应用于测氡仪的野外检测和响应实验，服务于地震监测预报和科研。
Industry to meet the current earthquake radon measurement instrument calibration and verification during the period of the need of verification, this paper USES the HD-min online than on micro radon chamber BG2015-R scintillation chamber radon measurement instrument calibration experiments, on the basis of JJG825-2013 the radon measurement instrument verification regulation of relevant technical requirements, selection of the concentration of 3000 Bq/m3 efficiency calibration test, the experiment shows that with the HD-min micro radon chamber calibration online than BG2015-R scintillation chamber of measuring radon measurement instrument is feasible. The HD-min micro radon chamber system can get rid of the regulatory restrictions of radium source, and can be applied to the field detection and response experiments of radon measuring instruments, and serve for seismic monitoring and prediction and scientific research.
