Title: System for air ²²²Rn activity concentration measurements based on ion-pulse ionization chamber detector

Abstract: This article presents the development, the testing and the efficiency estimation of a system for the monitoring of the atmospheric concentration of radon using a detector ionization chamber type in pulse mode for environmental measurements in which the measurement of the average value of the ionization current is completed with the recording of the impulses of the ionization current caused by the alpha disintegrations from the sensible volume of the detector.

Key words: ionizing radiation, radiation detector, radon system , alpha detector
