福州地震台P2000测氡仪试测实验分析
|
摘要
对P2000与FD-125测氡仪进行为期一个半月的同步观测对比,并对P2000测氡仪该装置是否适用于地震氡观测及氡气标定器的刻度校正进行测试实验,根据观测的数据进行归纳和总结。结果表明,P2000测氡仪稳定性较好,操作使用简单,一次性充电可以连续使用十几个小时,较适用于野外观测。缺点是该测氡1次只能测1个水样,如果要测两平行样要六七个小时,时间相对较长。对观测的数据对比分析,发现虽然P2000测氡仪测值低于FD-125氡钍分析器的测值,但整体形态和趋势变化基本一致。
Simultaneous comparative observation was done to radon detector of model P2000and model FD125at Fuzhou seismic station for one and half months to test whether the P2000 radon detector is suitable for earthquake radon observation.Trial measurement experiment was also done to correct the calibration of the radon calibration device.The result shows that the P2000 radon detector is a quite stable and easy operating instrument suitable for field observation.The disadvantage is that the P2000 radon detector can only measure one water sample in one measurement and will take 5~6 hours to give out two parallel observation samples.Comparative analysis of observation data indicates that though the measured radon value from P2000 is lower than FD-125,the whole pattern and changing trend of the observation are basically same.
