泉点改造对山西定襄七岩泉水氡影响

摘要

After reconstruction of Qiyan spring at Dingxiang,Shanxi Province in 2014, radon content in water decreased significantly. Through the analysis of various kinds of interference factors, making comparative observation, this falling of radon concentration in water of Qiyan spring at Dingxiang may be affected by the unsealed sampling after the reconstruction.%2014年定襄七岩泉泉点改造后，水氡含量大幅下降，通过分析排除各类干扰因素，进行对比观测认为，此次定襄七岩泉水氡浓度下降可能因泉点改造后取样口不密封所致。
