摘　　要：新疆地震局地球物理观测中心流体实验室目前测氡采用的仪器为FD-125,购置时间为1979年,由于长时间使用致该仪器老化严重,且没有备用仪器,无厂家生产更换。如果仪器出现故障未及时修理,缺少备用观测仪器,将会造成数据断测,影响观测数据的整体科学质量。因此,本文中以新疆水磨沟15泉水样为测量对象,引入DDL-2测氡仪在相同环境条件下与FD-125测氡仪进行检测并开展对比实验研究。研究表明:DDL-2测氡仪性能稳定,测值波动区间小,能满足前兆观测规范要求,能够正确反映地下水中氡含量的变化,研究认为DDL-2测氡仪有潜力代替FD-125测氡仪作为水氡日常测量仪器。The instrument used to measure radon in the underground fluid chamber of the Geophysical Observation Center of Earthquake Agency of Xinjiang Uygur Autonomous Region is FD-125,which was purchased in 1979.Due to the serious aging of the instrument for a long time,there is no spare instrument and no manufacturer to replace it.If the instrument fails to be repaired in time and there is a lack of spare observation instruments,it will cause data disconnection and affect the overall scientific quality of observation data.Therefore,in this paper,the water sample of Shuimogou 15 spring in Xinjiang is taken as the measurement object,and the DDL-2 radon detector is introduced to detect and compare with the FD-125 radon detector under the same environmental conditions.The results show that the DDL-2 radon monitor has stable performance and small fluctuation range of measured values,which can meet the requirements of precursory observation specifications and correctly reflect the change of radon content in groundwater.It is considered that the DDL-2 radon monitor has the potential to replace the FD-125 radon monitor as the daily measurement instrument of water radon.
