The results of the development of an experimental sample of a radiometer for measuring the concentration of radon in the air are presented. The application of an air pumping system and a combination of four Si planar detector plates made it possible to increase the sensitivity of the radiometer, which significantly expands its possibilities for use in both open and closed air ventilation systems. The developed software allows to measure and analyze the spectra of alpha particles in real time and evaluate the radon content in the specified time.
