Source: The EPA Radon in NC Zone Map is based on indoor radon screening samples compiled by the EPA, geologic and soil analysis, and foundation types to arrive at the zone characterizations.

NOTE: Radon data CAN NOT be used to predict whether a particular building or site will have elevated radon levels. Radon levels are highly site specific. The only way to know the radon level in a building is to conduct a radon test.
