Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

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

USGS geologic potential: Moderate across 58% of the county's area

Kent County, Compared

Kent County radon figures, compared

Calculated by Radon411

No CDC figure names Kent County, in any year or ten-year total; over the 2007 to 2016 laboratory totals, the agency's counts reach 140 Texas counties without it. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.

The nearest counties with a figure are Lubbock County (67 miles away) at 57.8%, Midland County (116 miles away) at 1.0% and Randall County (139 miles away) at 71.4%. Statewide for the same period, Randall County reported the highest share (71.4%) and Nueces County the lowest (0.0%).

EPA's 1993 map puts Kent County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 58% of the county's land moderate radon potential.

Kent County, Geology

The ground under Kent County

Predicted

USGS's geologic map splits Kent County: 58.1% of its land is moderate radon potential and 41.9% low. The map puts 58.1% of Kent County in the area it calls Northern High Plains and Plateaus and 41.9% in Central Texas. USGS gives the first a radon index of 10, in the moderate band (9 to 11), and the second 7, in the low band (5 to 8).
