Kemper County radon figures, compared

Calculated by Radon411

No Mississippi county, Kemper County included, has a radon test figure from CDC; over the 2006 to 2015 laboratory totals, the agency's counts name 2,669 counties in other states. Across every county in the country with a figure (2,669), 36.3% of reported tests reached that level; no Mississippi county contributes to that pool.

The nearest counties with a figure are Tuscaloosa County, AL (75 miles away) at 10.1%, Jefferson County, AL (115 miles away) at 10.6% and Autauga County, AL (117 miles away) at 12.8%.

EPA's 1993 map puts Kemper County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 87% of the county's land low radon potential.
