Note: This map is not comprehensive. Markers have been placed on streets where elevated radon levels (2.0 pCi/L and above) have been discovered. A lack of markers in a specific location does not necessarily indicate low radon levels; instead, it may indicate a lack of data.
Please contact us if you have any questions about the radon levels in your area.
