Radon tests reported for Moore County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Moore County over the 2008 to 2017 laboratory totals, with a median of 4.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Moore County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Moore 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).
Moore County, Compared
Moore County radon figures, compared
Calculated by Radon411CDC's largest figure for Moore 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 5.2 pCi/L, with a middle value of 4.7 pCi/L.
Potter County, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 20.0% of its tests at or above 4 pCi/L. Farther out, Randall County (60 miles away) at 71.4%, Lubbock County (154 miles away) at 57.8% and Midland County (274 miles away) at 1.0% 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 Moore 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.
Moore County, Geology
The ground under Moore County
PredictedUSGS's geologic map puts all of Moore 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% |

Moore County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Moore County's is. Of the 8 counties that border it, none has as large a share of moderate-potential ground; Carson County comes nearest at 100%.
The map rates the ground, not the air in any home.

Moore County, Cities and towns
Cities and towns in Moore County
The Census Bureau estimates 21,891 residents in Moore County for July 1, 2025, 627 more than in 2020 (+2.9%). That works out to 24 people per square mile of land.
