What these figures count
Only 11 tests were reported to CDC for Taney County over 2023, 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: 2023. Measured data period: 2005 to 2023 (every CDC figure on file).
Taney County, Compared
Taney County radon figures, compared
Calculated by Radon411In Taney County, about 4 in 10 reported tests over the 2008 to 2017 laboratory totals (54 of 146) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 1.3 points higher. Across 115 Missouri counties pooled together, 30.6% of tests reached that level, so Taney County runs 6.4 points above its state.
The newest figure, in 2023, counts only 11 tests (72.7% at or above 4 pCi/L), too few to compare, so this reading uses the 146-test figure.
Of 2 neighbours with a figure, 1 reported a larger share at or above 4 pCi/L and 1 a smaller one; the spread is 31.7% (Christian County) to 41.6% (Stone County). By share, Taney County is 24th of 72 Missouri counties with 30 or more tests for the same period.
Half the tests came in under 3.0 pCi/L and half over it; the single highest reached 111.2 pCi/L. Below the action level, 53 tests (36.3%) came in under 2 pCi/L, against 41.2% statewide, and 39 tests (26.7%) fell between 2 and 4, against 28.1% statewide.
Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 37.0% share point the same way here. USGS geology rates 100% of the county's land moderate radon potential. CDC also counts 9 tests taken after mitigation in Taney County for the same period: tests in homes where a fix was already in.
The busiest year on file was 2020, with 19 tests reported; the quietest, 2019, had 1.
Pooled shares: Radon411's sum of CDC's county counts for one period.

The ground under Taney County
PredictedUSGS's geologic map puts all of Taney County's mapped land in one class: moderate radon potential. 95.6% of it lies in the area the map calls Salem Plateau, to which USGS gives a radon index of 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Salem Plateau | Ordovician dolomite, sandstone, limestone, and shale. | Moderate | 11 | 95.6% |
| Springfield Plateau | Mississippian limestone, shale, and sandstone. | Moderate | 9 | 2.6% |

Taney County, Cities and towns
Cities and towns in Taney County
The Census Bureau estimates 57,001 residents in Taney County for July 1, 2025, 948 more than in 2020 (+1.7%). That works out to 90 people per square mile of land. Branson, the largest place on its list (12,921 residents in all), extends beyond Taney County, so no share of the total is worked out for it. Reported testing is thin here: 146 tests over 2008 to 2017, or 2.6 for every 1,000 residents (2025 estimate), where Missouri as a whole comes to 9.3.
From Branson to Kirbyville, CDC publishes no figure by town: each reads Taney County's.
