ABSTRACT:
Air contamination from deficiency of oxygen and/or the presence of unhealthy amounts of radon gas in a dwelling is controlled by the simple expedient of providing fresh air flow through a dwelling under conditions that keep the internal dwelling pressure above atmospheric, thereby prevention the radon gas from percolating through the earth adjacent the dwelling walls and floors and into the interior of the dwelling.
