水氡观测样品脱气温度及观测时间的选取

Selection on degasification temperature and observation time of radon observation sample

以天津王4井为例,论述了在水氡观测过程中,样品脱气温度和观测时间如何进行选取。水氡观测过程中影响因素很多,通过实验认为:针对不同的井孔,依据观测规范选取最佳的观测条件,从测值中可以系统的剔除或减少外界因素对氡观测的影响。

Taking the Wang 4 well in Tianjin as the example, how to select degasification temperature and observation time in observation process of water radon are discussed in this paper. There are a lot of affect factors in the water radon observation process. An experiment result shows that the influence of outside factors on radon observation may be eliminated or reduced by selecting the best observation condition according to the observation criterion and the condition of different boreholes.
