North Carolina Radon Program

What is Radon?

Radon is the leading environmental cause of lung cancer in the United States of America, second only to smoking tobacco.

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.
