【摘要】 通过分析KJD-2000R测氡仪(α谱仪)记录的下关温泉水中氡含量的4组α粒子能量脉冲数、氡含量以及影响观测结果因素,结合传统水氡观测仪器FD-125型室内氡钍分析器平行对比观测结果,认为:KJD-2000R测氡仪观测对象明确,而且自动鼓泡和读数,完全避免了人工鼓泡和读数引起的误差,对提高氡及其子体变化规律的认识,提高水氡观测资料质量及映震能力,充分捕获水氡前兆异常信息都具有一定实际意义,也为地震观测及台站水氡观测仪器选型提供参考。更多还原

【Abstract】 Combining the parallel observation of radon content in Xiaguan hot spring recorded by the traditional FD-125 indoor Radon-Thorium emanometer and KJD-2000R emanometer(alpha ray spectrometer)which is a new-type instrument of monitoring water radon content,we compared and analyzed 4-set of alpha energy pulse number,radon content and influence factors during observation.The results show that the KJD-2000R emanometer have some advantages than FD-125 emanometer,such as it has clear objects observed,can bubbling and reading automatically,so it can efficiently reduce errors caused by bubbling and reading artificially.These comparisons and tests will be helpful for improving understanding of variation of the radon and its daughter’s,and the qualities and earthquake reflecting ability of radon observation data.It has the certain practical significance for finding precursor abnormal information of water radon,and also provides the references for seismic observation and the type selection of water radon observation emanometers.更多还原
