Where Does Radon Come From?

Radon is the decay product of metals found in the earth’s crust. It is present in almost all rock, and all soil and water (EPA).

Once Radon gas forms it can seep into your home from exposed dirt from a crawl space, plumbing cut-out or old cellar. Radon gas can also pass through openings in your foundation such as unsealed sump pumps, drains, joints, cracks, and open top block walls. In certain areas radon may be found from drinking water that comes from private wells. The highest levels of radon are usually found in the lowest areas of the home, such as basements or other rooms in direct contact with the ground (VDH).
