Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

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

No CDC test figures here

CDC has published no radon test figures for Scott County. Tuscaloosa County, AL, 132 miles away, is the nearest county with a figure over the 2006 to 2015 laboratory totals.

How to read these figures

Scott County, Compared

Scott County radon figures, compared

Calculated by Radon411

CDC publishes no radon test figure for Scott County, and none for any other Mississippi county: its counts over the 2006 to 2015 laboratory totals cover 2,669 counties elsewhere in the country. 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 (132 miles away) at 10.1%, Tangipahoa Parish, LA (133 miles away) at 0.0% and Mobile County, AL (136 miles away) at 4.4%.

EPA's 1993 map puts Scott 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.

Scott County, Geology

The ground under Scott County

Predicted

USGS's geologic map puts all of Scott County's mapped land in one class: low radon potential. The map puts 61.2% of Scott County in the area it calls Jackson Prairies and 38.8% in North Central Hills/Flatwoods. USGS gives both a radon index of 8, in the low band (5 to 8).
