Locations and reports
EPA puts Wichita County in Zone 3, its lowest radon zone, and only 10 radon tests from it are on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

Measured: tests reported to CDC
CDC holds 10 reported tests for Wichita County over the 2008 to 2017 laboratory totals, with a median of 0.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Wichita County beside the counties around it is how this page reads it.
Only 10 tests were reported to CDC for Wichita County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Wichita County, Compared
CDC's largest figure for Wichita County rests on 14 tests over the 2006 to 2015 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 7.1 points and no rank or comparison is drawn from it. Results reached as high as 4.0 pCi/L, with a middle value of 0.8 pCi/L.
The nearest counties with a figure are Denton County (106 miles away) at 7.2%, Tarrant County (117 miles away) at 10.6% and Collin County (135 miles away) at 7.7%. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
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 Wichita 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.

Wichita County, Geology
USGS's geologic map puts all of Wichita County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Texas, to which USGS gives a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Texas | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 99.9% |
Names, descriptions and indexes: U.S. Geological Survey, Geologic Radon Potential Map (2025). Shares: Radon411, from the map cut to the boundary.
Across Texas 0.5% of the land is rated high; none of Wichita County's is. None of the 6 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
