摘要
针对目前台站测氡仪校准困难的问题,提出标准仪器校准法,并将其与RN-FD循环式氡气固体源进行对比,同时利用台站应用最为广泛的RN-150小型氡气固体源验证该方法的可行性。结果表明,利用RN-150小型氡气固体源及AlphaGUARD P2000F标准仪器分别对FD-125测氡仪3个闪烁室进行校准后得到的校准系数相对误差分别为0.2%、3.4%、2.8%,均达到目前地震监测中氡观测的技术要求,进一步验证了测氡仪标准仪器校准法的可行性。
In view of emanometer calibration difficulty present in earthquake stations,we advance a standard instrument calibration method for emanometer,compare it with RN-FD circulating radon gas solid source,and use RN-150 small radon gas solid source,which is the most widely used gas in current stations,to verify the feasibility of this method.The results show that the three scintillation chambers of FD-125 emanometer are calibrated by using RN-150 small radon gas solid source and AlphaGUARD P2000F emanometer;the relative deviations of the calibration coefficient are 0.2%,3.4%and 2.8%,meeting the technical requirements of radon observation in seismic monitoring,verifing that the standard instrument calibration method is feasible.
