A method for increasing a detection sensitivity of a radon monitor based on an electrostatic collection method and a device thereof increase the detection sensitivity of the radon monitor based on the electrostatic collection method through increasing a collection efficiency of positively charged 218Po in an internal cell of the radon monitor based on the electrostatic collection method. A metal mesh is provided between a wall of the internal cell and a semiconductor detector to increase an electric field intensity close to the wall of the internal cell. A ground wire of a high-voltage module ...
