What is Radon?

Radon is a dangerous naturally occurring radioactive gas that you can not see, smell or taste. 

Health Risk

Exposure to Radon is considered second only to smoking as the leading cause of lung cancer.

Lung cancer is the only health effect that is certainly linked with radon exposure. In addition, Radon exposure can also impact Indoor Air quality (IAR).

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).
