This paper elaborates on the causes of errors in the measuring of surface α activity in highly humid environment by analyzing the effect of relative humidity on air density and surface adsorption.With the use of Φ45mm α source,surface activity response factors of MicrocontⅡ surface α β measuring instrument are measured in 5 different relative humidity conditions at 20℃,thus basically showing the law of relative humidity affects the measuring of surface α activity,which can provide a reference for measuring surface α activity in highly humid conditions.
