Nevada Test Results

The Nevada Radon Education Program compiles short-term radon test results that were completed by Nevada homeowners from 1989 to the present. The results have been compiled for each county by zip code and a corresponding geographical information systems (GIS) map based on zip codes has been designed. The map provides an indication of radon potential by zip code and is not intended as a guide to determine whether a radon test is needed, but rather an indication of the prevalence of elevated radon levels in a zip code area. The maps are not to be used in lieu of testing during real estate transactions, and should not be used to determine if individual homes in any given area need to be tested for radon. Nevada Division of Public and Behavioral Health recommends that all homes be tested for radon, regardless of geographic location or the zone designation of the county in which they are located. The maps are intended to be a starting point for characterizing radon potential.

Radon results are based on independently tested homes, not scientific sampling. When known, post-mitigation results are not included and include only valid test results. When more than one test is completed per home, an average is obtained, using results from the lowest level of the home tested.
