| Map of Radon Zones for Ohio | ||||||||||
![]() 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.
