Lafayette County radon figures, compared

Calculated by Radon411

Lafayette County has no radon test figure of its own from CDC, whose counts over the 2007 to 2016 laboratory totals name 60 other Arkansas counties and leave it out. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.

The nearest counties with a figure are Garland County (96 miles away) at 45.8%, Saline County (111 miles away) at 31.9% and Pulaski County (129 miles away) at 6.8%. Statewide for the same period, Garland County reported the highest share (45.8%) and Pulaski County the lowest (6.8%).

EPA's 1993 map puts Lafayette 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.
