Wilcox County, Compared

Wilcox County radon figures, compared

Calculated by Radon411

Wilcox County has no radon test figure of its own from CDC, whose counts over the 2008 to 2017 laboratory totals name 65 other Alabama counties and leave it out. Pooled across 65 Alabama counties, 21.9% of reported tests reached that level; across every county in the country with a figure, 35.7%.

The nearest counties with a figure are Autauga County (54 miles away) at 17.1%, Montgomery County (66 miles away) at 9.7% and Elmore County (80 miles away) at 22.2%. Statewide for the same period, Colbert County reported the highest share (36.2%) and Baldwin County the lowest (0.0%).

EPA's 1993 map puts Wilcox County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 84% of the county's land low radon potential.

The ground under Wilcox County

Predicted

Most of the ground under Wilcox County is one class on USGS's geologic map: 83.7% of its land is low radon potential, with 16.3% moderate. The map puts 83.7% of Wilcox County in the area it calls Coastal Plain and 16.3% in Inner Coastal Plain. USGS gives the first a radon index of 7, in the low band (5 to 8), and the second 10, in the moderate band (9 to 11).
