Radon Maps

Note: These maps only show average values. Indoor radon varies substantially at scales not shown on these maps. It is not wise to use these maps to predict the radon in an individual house. Rather, these maps can be used to estimate the average indoor radon on a local or regional scale.
ATD maps rely on long term(>90 day) radon measurements using alpha track detectors while CC maps are based on short-term (2day) measurements using charcoal canister radon detectors. Contour maps are created from point data sets (radon value and location). Others maps generated by taking the average within a geopolitical boundary (county/state_province/country).
