It's a little-known fact that radon, a colorless, odorless, radioactive gas found in the earth's rock and soil is the second leading cause of lung cancer. Radon occurs naturally and is produced by the breakdown of uranium in soil, rock, and water. It is classified as a Group A carcinogen; that is, it is known to cause cancer in humans with prolonged exposure. Many buyers are concerned about the health risk, as well as the resale value of their home and want to test for and correct radon concerns.
