What these figures count
Only 5 tests were reported to CDC for Pulaski 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).
Pulaski County, Compared
Pulaski County radon figures, compared
Calculated by Radon411Pulaski County's 107 reported tests over the 2008 to 2017 laboratory totals had a middle value of 1.3 pCi/L and a maximum of 69.5 pCi/L, and 18.7% reached 4 pCi/L. Missouri as a whole (115 Missouri counties, pooled) comes to 30.6%: 11.9 points higher than here.
The newest figure, in 2023, counts only 5 tests (20.0% at or above 4 pCi/L), too few to compare, so this reading uses the 107-test figure.
Among its state's counties it ranks 63rd of 72 Missouri counties with 30 or more tests for the same period. Statewide for the same period, Atchison County reported the highest share (69.9%) and Vernon County the lowest (8.8%).
Below the action level, 69 tests (64.5%) came in under 2 pCi/L, against 41.2% statewide, and 18 tests (16.8%) fell between 2 and 4, against 28.1% statewide. The busiest year on file was 2018, with 6 tests reported; the quietest, 2021, had 1.
EPA's 1993 zone map puts Pulaski County in Zone 2, a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
Next door, the shares run from 14.7% in Phelps County to 37.0% in Laclede County, with Miller County and Phelps County below Pulaski County.

The ground under Pulaski County
PredictedUSGS's geologic map puts all of Pulaski County's mapped land in one class: moderate radon potential. All 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 | 100% |
