ABSTRACT:
A radon measuring device having a housing formed of at least two mating portions and coupled together by a fastener. At least one aperture extends through the housing to permit ambient atmosphere to enter the housing and includes a filter or membrane positioned to cover the aperture for filtering radon from other particles from the ambient atmosphere as it enters the housing. A radon detector is positioned within the housing for measuring the concentration of radon in the ambient atmosphere which passes through the aperture and the filter into the housing. A filter support member also is inclined for positioning the filter proximate the aperture and pressing the filter against the housing.
