![]() Click on the image for a larger version | What do the colors mean? |
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. Learn more | ||||||||||||

Directory of Builders as a one-stop service to home buyers who are looking for builders that use radon-resistant construction techniques in new homes.
