Nebraska Radon Program
Radon in Nebraska

Nebraska has a very high incidence of radon in homes; over half of radon tests in the state are above the action level of 4.0 pCi/L.

The Nebraska Radon Program collects testing information from across the state and periodically produces maps and tables reflecting summary data. The purpose of this summary data is to assist organizations to target their resources and to implement radon-resistant building codes.

Maps and tables are not intended to be used to determine if a home in a given area should be tested for radon. Homes with elevated levels of radon have been found in all areas of the state. All homes should be tested regardless of geographic location.
