The radon map used by the Environmental Protection Agency (E.P.A.) was developed using five
factors to determine radon potential within a local or regional area of the U.S.
indoor radon measurements;
soil permeability; and
The E.P.A. states 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.
Note: This map should not be used for
testing purposes for real estate transactions.
These zones only indicate a potential for radon gas in your home and does not mean it may be
present. For instance; neighborhoods which may be built upon ground which has rock formations underneath may be
more likely to have radon gas than not since radon is a by-product of degrading rock.
The E.P.A. suggest that all homes should be tested at some time regardless of location. Most
states have a designated radon contact and either offer free or discounted tests kits to the public. Some states
require that you hire a contractor on your own to determine your home radon risk. In addition, some home
improvement centers may offer do-it-yourself radon test kits.
