MISSOURI - EPA Map of Radon Zones
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 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 zone designation.
