National Radon Directory
The National Radon Directory is the only database that consolidates state and county specific radon information into one centralized location for the benefit of local search capabilities and national research. In addition to the database, the National Radon Directory provides access to unique tools and reporting that will help increase awareness of the dangers of Radon. The directory can be accessed by browsing the state directory below or by using one of the search tools. You can search radon levels by zip code or search radon levels by county.
The National Radon Directory is an ongoing effort to create an up to date, national database of radon information that is convenient to search. If you find any errors or have any suggestions on the data we provide, please contact us here.
