Gamma radiation compensated radon measurement system
Description
This patent describes a radon measurement system. It comprises means for defining a first sensing volume (SV1) and a second sensing volume (SV2); a first electret (E1) mounted to attract ions generated in the first sensing volume as a consequence of radon decay or gamma radiation therein; and a second electret (E2) mounted to attract ions generated in the second sensing volume as a consequence of radon decay or gamma radiation therein, the relative sensitivity of the second sensing volume to radon and gamma radiation being different from that of the first sensing volume
