Radon is a colorless, odorless radioactive gas that forms when naturally occurring uranium decays. Radon gas is commonly found in rocks and soil, and it enters homes through cracks and other holes in the foundation. Prolonged exposure to radon levels above 4 picocuries per liter of air significantly increases the risk of lung cancer, even for nonsmokers. The USEPA considers radon the second leading cause of lung cancer in the United States overall, and it is the leading cause among non-smokers.
The only way to find out if you have elevated radon levels in your home is to conduct a simple test.

Is there an “acceptable” level of radon?
USEPA has established 4 picocuries / liter of air as the “Action Level” for radon in a home.
How does radon get into my home?
Radon is a radioactive gas that is naturally occurring in the soil and bedrock. It enters the home (usually the basement or slab) through cracks, holes, and other openings.
What do I do if my test results exceed 4.0 picocuries / liter?
Currently, no law requires a homeowner to mitigate the radon. However, if you sell your home in the future, you must disclose that a radon test was conducted, and what level of radon was detected. If you choose to have radon mitigation done, visit the State of Ohio's website and click on "Find a Licensed Radon Contractor in Your Area" on the left side of the page.
