| 摘 要： | 论述了FD-125测氡仪在水氡观测中值得注意的几个问题：①仪器的供电系统中不应有线路接触不良；②仪器接地线应避免接触不良；③其他用电器内部线路也不应有接触不良；④引起电场和磁场变化的大功率用电设备不应在测量时间内使用；⑤供电电路中电压尽可能避免大幅度波动等。上述因素对氡测值都有影响，影响幅度可达10％以上。

| Abstract: | We have discussed some noticeable issues which affect the ratio of Radon in underground water observed by FD- 125 Rn instrument. Every part of the instrument should avoid loose link, especially the ground line and the inner circuits of the related electric instruments. Also,strong powered equipments that will cause changes in electric and magnetic field should not be used during the observing period. Besides, the voltage in the main supply can not have great fluctuation. All above factors would greatly influence on the observing results of Radon, whose range may come up to 10 percent or more. |
