Lynn County, Compared

Lynn County radon figures, compared

Calculated by Radon411

No CDC figure names Lynn 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%.

Lubbock County, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 57.8% of its tests at or above 4 pCi/L. Farther out, Midland County (91 miles away) at 1.0%, Randall County (123 miles away) at 71.4% and Potter County (153 miles away) at 20.0% have figures too. 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 Lynn County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 70% of the county's land moderate radon potential.

Lynn County, Geology

The ground under Lynn County

Predicted

USGS's geologic map splits Lynn County: 69.8% of its land is moderate radon potential and 30.2% low. The map puts 69.8% of Lynn County in the area it calls Northern High Plains and Plateaus and 30.2% in Southern High Plains and Plateaus. 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).
