静电收集法测量氡浓度的两种技术路线比较
Comparison of Two Kind Technology Methods of Electrostatic Collection for Radon Measurement
摘要
Abstract
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 measurement,but the delay time of measurement can be minor,and the desiccant does not need replacement.It is especially suitable for unattended long-term continuous measurement of radon concentration.关键词
