Improvement and data analysis of radon gathering device of soil gas in Well No.3 of Huailai County

In order to solve the observation data quality problems caused by the influence of the surrounding environment on the soil gas radon gathering device in Well No.3 of Huailai County, the depth and position of the new soil radon observation borehole and the gathering device were selected and designed by AlphaGUARD series P2000 radon measuring instrument. Data results show that the new soil gas radon gas-gathering device ensures the underground gas effective collection, observation data daily variation rules, dynamic stability and the inner quality obviously improve at the same time, the observed data and reliable credible, can more truly reflect the variations of soil gas radon concentration in Well No.3 of Huailai County, which ensure the continuity of soil gas radon observation data.
