摘要
氡气测量结果受地表各种因素的影响，如土壤湿度、测孔中的温度、气候等。一般土壤湿度变化不大时，湿度对测量结果影响不大；当土壤湿度达１００％时，即测孔中有水情况下，取样片的吸附能力大大减弱。通过晴天、雨天、雨后实测试验表明，晴天氡气异常比雨天或雨后天气要明显的多。
he results of the radon measurement are affected by many factors, for instance, thehumiduty of the soil, the temperature in the detecting hole, climate, etc. The results don't generally change as the humiduty of the soil changes. When the humiduty of the soil is 100% in the detecting hole, the absorbert capacity of the sampling chip is much weaken. Through the experimentof the radon measurement in the fine day, the rain day and after rain, it explains that the peaksof the radon anomalies is much higher in a fine day than in a rainy day.
