Radon is a colorless, odorless, tasteless, and chemically inert radioactive gas. It is formed by the natural radioactive decay of uranium in rock, soil, and water. It can be found in all 50 states. Testing for it is the only way of telling how much is present.
Radon Gas is a silent killer. Recent studies have confirmed the EPA and Surgeon General estimates that as many as 20,000 lung cancer deaths are caused each year by radon in the United States. If your home or building has tested high for radon, the EPA recommends radon mitigation.
What does EPA recommend?
If you are buying a home or selling your home, have it tested for radon.
For a new home, ask if radon-resistant construction features were used and if the home has been tested.
Fix the home if the radon level is 4 picocuries per liter, or pCi/L, or higher.
Radon levels less than 4 pCi/L still pose a risk, and in many cases, may be reduced.
Take steps to prevent device interference when conducting a radon test.
