The continuous radon monitor,based on the electrostatic collection,has been widely used at present.However,the collection efficiency of the positively-charged radon progeny in the electrost aticfield is influenced by air humidity.By analyzing the two technical routes,we find that this problem canbe solved by using drying tubes and the measured value is of high accuracy,but the delay effect of measurement from the gap of the tube increase at the same pump flow rate.Using the temperature and humidity correction curve will lead to additional measurement error due to temperature and humidity measu...
