Beschreibung
Zusammenfassung:	A device for measuring Radon gas concentrations comprises a measuring chamber (20) equipped with a detecting device (23), adapted to detect alpha particles from Radon gas; the device of the invention further comprises a collecting electrode (22) external to the measuring chamber (20), adapted to collect the electrically charged decay products of Radon coming from the measuring chamber (20). A control unit (30) times the passage between two operating stages (I, II) in which the detecting device (23) and the collecting electrode (22) are active at different times.
