EPA Map of Radon Zones including State Radon Information and Contacts

Find local information related to radon, including your state radon program, with contact information, EPA Regional contacts and a state-specific map.

The purpose of this map is to assist national, state and local organizations to target their resources and to implement radon-resistant building codes. This map is not intended to be used to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested regardless of geographic location.
