How does radon enter my home?
Radon can enter a home anywhere there is an opening between the home and the soil as well as through solid material. These openings include dirt floor crawl spaces, cracks in slab-on-grade floors, and concrete block walls. As air is used or exhausted from the home, this "lost" air creates a vacuum (suction) in the home which then pulls in air from the outside. Some of this outside air comes from the soil, which may contain high levels of radon.
