摘　　要：为解决怀3井土壤气氡集气装置因周边环境影响造成的观测数据质量问题,用AlphaGUARD系列P2000测氡仪对新土壤气氡观测钻孔深度、位置及集气装置进行了选点并设计改造。数据结果显示:新土壤气氡集气装置保障了地下气体有效的收集,观测数据日变化规则,同时动态稳定性及内在质量明显提高,观测数据可靠可信,能较为真实地反映怀3井土壤气氡浓度变化,保证了土壤气氡观测资料的延续性。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.
