EPA Zone 3: lower predicted potential

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

Miller County, Compared

Miller County radon figures, compared

Calculated by Radon411

Miller County has no radon test figure of its own from CDC, whose counts over the 2007 to 2016 laboratory totals name 137 other Georgia counties and leave it out. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.

The nearest counties with a figure are Dougherty County (40 miles away) at 0.0%, Muscogee County (93 miles away) at 2.1% and Harris County (109 miles away) at 10.9%. Statewide for the same period, Barrow County reported the highest share (51.0%) and Dougherty County the lowest (0.0%).

EPA's 1993 map puts Miller County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Miller County, Geology

The ground under Miller County

Predicted

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