Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Wilkinson 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.

Wilkinson County, Geology

The ground under Wilkinson County

Predicted

USGS's geologic map puts all of Wilkinson County's mapped land in one class: low radon potential. The map puts 49.3% of Wilkinson County in the area it calls Pine Hills and 35.3% in Loess Hills, with one smaller area beside them. USGS gives the first a radon index of 6 and the second 7, both in the low band (5 to 8).
