Radon

Radon is an odorless, tasteless, invisible gas that is a product of naturally-occurring uranium. According to the U.S. EPA, one in every 15 homes in the United States have radon levels that exceed the recommended radon action level.

The Surgeon General reports that radon gas is the second leading cause of lung cancer in the United States, second only to cigarette smoking. It is estimated that radon causes 20,000 deaths annually. People who smoke and are exposed to high levels of radon are especially at risk of acquiring lung cancer.

The above map is not intended to determine if a home in a given zone should be tested for radon. Homes with elevated radon have been found in all three zones. All homes should be tested regardless of geographic location. It is recommended that homes are tested every two years.

Blue – Zone 1 – High potential
Yellow – Zone 2 – Moderate
Green – Zone 3 – Low potential
