Radon is an odorless, colorless radioactive gas found in our environment. Cortland County has the highest average indoor radon level in the New York State. The majority of homes in the county have radon readings above the U.S. EPA action level of 4 piCu/l of air. The gas can become trapped in buildings. Radon is the second leading cause of lung cancer in the United States.

The Cortland County Health Department encourages radon testing in the homes and remediation when necessary. Each year the Environmental Health Division has a limited number of free radon test kits for homeowners. These kits are distributed during the heating season of October through April.
