Locations and reports
EPA puts Luna County in Zone 2, its middle radon zone, and only 5 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 5 reported tests for Luna County over the 2008 to 2017 laboratory totals, with a median of 2.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Luna County beside the counties around it is how this page reads it.
Only 5 tests were reported to CDC for Luna 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).
Luna County, Compared
CDC's largest figure for Luna County rests on 16 tests over the 2005 to 2014 laboratory totals, 5 of them at or above 4 pCi/L, so each test moves its share by 6.3 points and no rank or comparison is drawn from it. Results reached as high as 6.6 pCi/L, with a middle value of 2.5 pCi/L.
Doña Ana County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 16.3% of its tests at or above 4 pCi/L. Farther out, Otero County (121 miles away) at 10.7%, Lincoln County (171 miles away) at 20.6% and Bernalillo County (207 miles away) at 25.2% have figures too. Pooled across 30 New Mexico counties, 30.3% of reported tests reached that level; across every county in the country with a figure, 36.3%.
Statewide for the same period, Taos County reported the highest share (71.9%) and Otero County the lowest (10.7%). EPA's 1993 map puts Luna County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 88% of the county's land low radon potential.

Luna County, Geology
Most of the ground under Luna County is one class on USGS's geologic map: 88.3% of its land is low radon potential, with 11.7% moderate. The map puts 88.3% of Luna County in the area it calls Basin and Range Southern Mexican Highland and 11.7% in Datil-Mogollon Volcanic Field. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Basin and Range Southern Mexican Highland | Volcanic, plutonic, and lesser sandstone, shale, limestone; Quaternary velley-fill alluvium. | Low | 8 | 88.3% |
| Datil-Mogollon Volcanic Field | Silicic to intermediate volcanic and volcaniclastic rocks, basin-fill gravel, sand, silt. | Moderate | 11 | 11.7% |

Across New Mexico 19.2% of the land is rated high; none of Luna County's is. Of the 4 counties that border it, 2 have more high-potential ground, Sierra County the most at 50.4%.

No CDC figure names Luna County; the nearest county with one, Doña Ana County (55 miles away), reported 16.3% of its tests at or above 4 pCi/L over the 2006 to 2015 laboratory totals, the only reading nearby until a test of this home. In Zone 2 a short-term kit (2 to 90 days) is the quick first check in Luna County; a long-term test tells the year-round average.

Luna County, Cities and towns
Luna County's population has barely moved since 2020: 25,407 residents on July 1, 2025 against 25,452 then, by the Census Bureau's estimates. Spread over its land, that is 8.6 people to the square mile. Deming alone is home to 14,944 of them, 58.8% of the total. Together its 2 incorporated places hold 64.7% of those residents; the other 35.3% live outside any of them. Reported testing is thin here: 16 tests over 2005 to 2014, or 0.6 for every 1,000 residents (2025 estimate), where New Mexico as a whole comes to 2.2.
From Deming to Columbus, CDC publishes no figure by town: each reads Luna County's.
