Schleicher County radon figures, compared

Calculated by Radon411

No CDC figure names Schleicher 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 Midland County (111 miles away) at 1.0%, Bexar County (157 miles away) at 6.6% and Travis County (169 miles away) at 9.3%. 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 Schleicher 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.
