摘要：
A new radon monitor with a 50 mL hemispherical internal cell (Hynu EIRM) is designed to develop a radon monitor with less influence of humidity based on electrostatic collection and CR-39. The collection efficiency of Po-218 ions in the Hynu EIRM while the cell-wall voltage is 2000 V is estimated by a model established previously. The collection efficiency of Po-218 ions under the relative humidity of 1% is 4.81% higher than that under the relative humidity of more than 10%. Several verification experiments are performed. The Hynu EIRMs are use...
