新型水氡仪校准及台站比测实验研究
Experimental study on calibration and station comparison of a novel water radon meter
摘要
Abstract
Using the AlphaGUARD P2000F radon detector as the standard instrument,this study calibratedthe novel water radon meter DDL-2 and carried out acomparative observation experiment of the DDL-2 water radon meter and the FD-125 radon meter under the same observation environment.The experiment results show that the relative deviation of the calibration K value of the main sample chamber and the secondary sample chamber is less than 5%when the static time is 2 hours,which meets the calibration requirements of the radon measuring instrument in the current technical specification for seismic subsurface fluid observation.In spite of the different radon measuring principles,the radon measuring values of the DDL-2 water radon meter and the FD-125 water radon meter have good consistency and synchronization.Compared with the analog radon instrument widely used in the earthquake monitoring system,the novel DDL-2 water radon meter has a higher level of automation and digitization in the operation process,which can reduce the error caused by manual operation in daily analog observation and improve the quality of radon monitoring data.The overall design of the instrument basically meets the needs of the development demand of radon observation technology for earthquake underground fluid.关键词
