Radon tests reported for Carson County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Carson County over the 2008 to 2017 laboratory totals, with a median of 36.2 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Carson County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Carson 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.
Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Carson County, Compared
Carson County radon figures, compared
Calculated by Radon411CDC's largest figure for Carson County rests on 2 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 61.2 pCi/L, with a middle value of 36.2 pCi/L.
Of the counties bordering it, 2 have a figure over the 2007 to 2016 laboratory totals: Randall County reported the largest share at or above 4 pCi/L, 71.4%, and Potter County the smallest, 20.0%. Farther out, Lubbock County (126 miles away) at 57.8%, Midland County (247 miles away) at 1.0% and Denton County (286 miles away) at 7.2% have figures too. 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 Carson County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Carson County, Geology
The ground under Carson County
PredictedUSGS's geologic map puts all of Carson County's mapped land in one class: moderate radon potential. All of it lies in the area the map calls Northern High Plains and Plateaus, to which USGS gives a radon index of 10, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Northern High Plains and Plateaus | Tertiary sandstone, siltstone, shale. | Moderate | 10 | 100% |

Carson County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Carson County's is. Of the 8 counties that border it, none has as large a share of moderate-potential ground; Hutchinson County comes nearest at 100%.

Carson County, Cities and towns
Cities and towns in Carson County
Carson County's population has barely moved since 2020: 5,805 residents on July 1, 2025 against 5,795 then, by the Census Bureau's estimates. Spread over its land, that is 6.3 people to the square mile. Its largest town, Panhandle, has 2,288 residents, 39.4% of the total. Together its 4 incorporated places hold 73.8% of those residents; the other 26.2% live outside any of them. Testing is reported here more often than across the state: CDC's 2 reported tests for 2008 to 2017 come to 0.3 for every 1,000 residents (2025 estimate), against 0.1 for Texas.
From Panhandle to Skellytown, CDC publishes no figure by town: each reads Carson County's.
