Can the radon concentration in the building be reduced due to controlled room ventilation?

Radon has fallen into disrepute mainly in the English speaking countries as a major origin of lung cancer. It exists in various concentrations in the soil and diffuses through the walls and mainly through leakages in the cellar into the building.

The radon concentration can be reduced due to proper ventilation of the building in any case. In contrast to exhaust air systems, which aspirate air through all leakages in the building envelope by means of negative pressure, the controlled room ventilation system involving supply air and exhaust air of the company Pluggit GmbH provides the advantage that the place, where the fresh air is aspirated, can be freely chosen. The aspiration of radon from the ground soil can thus be excluded.
