How RADON enters your home



Radon, being a gas can migrate through small spaces (voids) in the soil and rock. It can seep into a home or building undetected through dirt, floor cracks, sump pits, basement floor drains, around jack posts, foundation cracks and any other opening that would allow gas to flow. Concrete block walls are particularly porous allowing radon to migrate in.


Atmospheric air pressure inside a building is usually lower than the surrounding soil and foundation. As a result, this allows radon and other dangerous soil gases to be drawn into the building through openings in the foundation where it is in contact with the ground.





Radon levels can vary from area to area, home to home and even apartment to apartment.  House construction can also affect radon levels. However, radon can be a problem in all types of homes: old homes, new homes, drafty homes, insulated homes, homes with basements and homes without basements.
