Radon tests reported for Dickson County, 2023
| Year | Share of reported tests at or above 4 pCi/L |
|---|---|
| 2022 | 18.2% |
| 2023 | 50.0% |
2023: 50.0%. Across these years the share ran from 18.2% to 50.0%. Each column counts radon tests reported to CDC that year, not homes.
What these figures count
Only 2 tests were reported to CDC for Dickson 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).
Dickson County, Compared
Dickson County radon figures, compared
Calculated by Radon411Dickson County's 209 reported tests over the 2008 to 2017 laboratory totals had a middle value of 2.1 pCi/L and a maximum of 38.0 pCi/L, and 26.3% reached 4 pCi/L. Tennessee as a whole (95 Tennessee counties, pooled) comes to 33.3%: 7.0 points higher than here.
The newest figure, in 2023, counts only 2 tests (50.0% at or above 4 pCi/L), too few to compare, so this reading uses the 209-test figure.
Among its state's counties it ranks 46th of 80 Tennessee counties with 30 or more tests for the same period. Statewide for the same period, Jefferson County reported the highest share (56.8%) and Chester County the lowest (0.0%).
Below the action level, 98 tests (46.9%) came in under 2 pCi/L, against 42.4% statewide, and 56 tests (26.8%) fell between 2 and 4, against 24.3% statewide. The busiest year on file was 2022, with 33 tests reported; the quietest, 2023, had 2.
EPA's 1993 zone map puts Dickson County in Zone 2, a predicted county average between 2 and 4 pCi/L. USGS geology rates 73% of the county's land moderate radon potential.
Next door, the shares run from 23.8% in Humphreys County to 35.0% in Hickman County, with Williamson County and Humphreys County below Dickson County.
CDC also counts 5 tests taken after mitigation in Dickson County for the same period: tests in homes where a fix was already in.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Dickson County, Geology
The ground under Dickson County
PredictedUSGS's geologic map splits Dickson County: 73.2% of its land is moderate radon potential and 26.8% high. The map puts 73.2% of Dickson County in the area it calls Highland Rim and 26.8% in Cherty Highland. USGS gives the first a radon index of 11, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Highland Rim | Paleozoic sedimentary rocks (limestone, shale, chert, and dolostone). | Moderate | 11 | 73.2% |
| Cherty Highland | Cherty dolostone. | High | 12 | 26.8% |
