Locations and reports
EPA puts Yoakum County in Zone 3, its lowest radon zone, and only 3 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 3 reported tests for Yoakum County over the 2008 to 2017 laboratory totals, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Yoakum County beside the counties around it is how this page reads it.
Only 3 tests were reported to CDC for Yoakum 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).
Yoakum County, Compared
CDC's largest figure for Yoakum County rests on 3 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 2.5 pCi/L, with a middle value of 1.1 pCi/L.
Lea County, NM, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 13.3% of its tests at or above 4 pCi/L. Farther out, Lubbock County (66 miles away) at 57.8%, Midland County (101 miles away) at 1.0% and Randall County (135 miles away) at 71.4% 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 Yoakum 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.

Yoakum County, Geology
Most of the ground under Yoakum County is one class on USGS's geologic map: 99.8% of its land is low radon potential, with 0.2% moderate. All of it lies in the area the map calls Southern High Plains and Plateaus, 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 |
|---|---|---|---|---|
| Southern High Plains and Plateaus | Paleozoic and Mesozoic sandstone, limestone, shale. | Low | 7 | 99.8% |

Across Texas 0.5% of the land is rated high; none of Yoakum County's is. Of the 5 counties that border it, 2 have more moderate-potential ground, Lea County, NM the most at 88.3%.

Yoakum County, Cities and towns
About 7,438 people live in Yoakum County by the Census Bureau's estimate for July 1, 2025, 234 fewer than in 2020 (−3.1%). Spread over its land, that is 9.3 people to the square mile. Denver City, the largest place on its list (4,311 residents in all), extends beyond Yoakum County, so no share of the total is worked out for it. Testing is reported here more often than across the state: CDC's 3 reported tests for 2008 to 2017 come to 0.4 for every 1,000 residents (2025 estimate), against 0.1 for Texas.
From Denver City to Plains, CDC publishes no figure by town: each reads Yoakum County's.
| Place | Residents | Since 2020 | Share of residents |

2 incorporated places, as listed in the U.S. Census Bureau’s 2020 place reference files. Residents: U.S. Census Bureau population estimates for July 1, 2025 (Vintage 2025). A place that extends beyond Yoakum County is counted whole, so it has no share.
Yoakum County, Homes
Yoakum County is a place of houses on their own lots: 79% of its 3,015 homes are detached single-family houses, against 65% across Texas.
