2023: 28.6%. Across these years the share ran from 22.2% to 28.6%. Each column counts radon tests reported to CDC that year, not homes.
Only 7 tests were reported to CDC for Cheatham 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.

Cheatham County, Compared
In Cheatham County, about 3 in 10 reported tests over the 2008 to 2017 laboratory totals (70 of 205) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 1.6 points lower. Across 95 Tennessee counties pooled together, 33.3% of tests reached that level, so Cheatham County runs 0.8 points above its state.
The newest figure, in 2023, counts only 7 tests (28.6% at or above 4 pCi/L), too few to compare, so this reading uses the 205-test figure.
Of 5 neighbours with a figure, 1 reported a larger share at or above 4 pCi/L and 4 a smaller one; the spread is 25.8% (Williamson County) to 36.4% (Davidson County). By share, Cheatham County is 33rd of 80 Tennessee counties with 30 or more tests for the same period.
Half the tests came in under 2.3 pCi/L and half over it; the single highest reached 26.7 pCi/L. Below the action level, 95 tests (46.3%) came in under 2 pCi/L, against 42.4% statewide, and 40 tests (19.5%) fell between 2 and 4, against 24.3% statewide.
Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 34.1% share point the same way here. USGS geology rates 79% of the county's land high radon potential. CDC also counts 8 tests taken after mitigation in Cheatham County for the same period: tests in homes where a fix was already in.
The busiest year on file was 2022, with 27 tests reported; the quietest, 2023, had 7.

USGS gives the first a radon index of 12, in the high band (12 to 17), and the second 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Cherty Highland | Cherty dolostone. | High | 12 | 76.0% |
| Highland Rim | Paleozoic sedimentary rocks (limestone, shale, chert, and dolostone). | Moderate | 11 | 21.0% |
| Nashville Basin | Mississippian Limestone. | High | 14 | 3.1% |
