Radon Map
Zone 1 Highest Potential (greater
than 4 pCi/L)
Zone 2 Moderate Potential
(from 2 to 4 pCi/L)
Zone 3 Low Potential
(less than 2 pCi/L)
The
U.S. EPA and the U.S. Geological Survey have evaluated
the radon potential in the U.S. and have developed
this map is to assist National, State, and local organizations
to target their resources and to assist building code
officials in deciding whether radon-resistant features
are applicable in new construction. 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. The map assigns each of the 3,141 counties
in the U.S. to one of three zones based on radon potential.
Each zone designation reflects the average short-term
radon measurement that can be expected to be measured
in a building without the implementation of radon
control methods. The radon zone designation of the
highest priority is Zone 1.

Opinion
vs. Science: The public ranks radon as the
29th largest environmental health risk. However, the
scientific community ranks radon the number one biggest
risk (tied with worker chemical exposure).
