How does Radon get into homes?
Radon is a soil gas that typically moves up through the ground to the air above. Air pressure inside a home is usually lower than pressure in the soil around the home’s foundation. Homes draw Radon in through dirt floors, hollow-block walls, cracks in the foundation floor and walls, and openings around floor drains, pipes and sump pumps. Any home may have a Radon problem, including new, old, well-sealed or drafty homes. Radon is generally more concentrated on the lower levels, such as basements, ground floors and first floors.
Radon is a soil gas that typically moves up through the ground to the air above. Air pressure inside a home is usually lower than pressure in the soil around the home’s foundation. Because of the difference in pressure, a house acts like a vacuum, drawing radon in through dirt floors, hollow-block walls, cracks in the foundation floor and walls, and openings around floor drains, pipes and sump pumps. Any home may have a radon problem. This includes new, old, well-sealed or drafty homes, and homes with or without basements. Radon is generally more concentrated at lower levels, like basements, ground floors and first floors.
