Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Lincoln County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

The ground under Lincoln County

Predicted

USGS's geologic map puts all of Lincoln County's mapped land in one class: low radon potential. All of it lies in the area the map calls Pine Hills, to which USGS gives a radon index of 6, in the low band (5 to 8).
