What these figures count
Only 11 tests were reported to CDC for Levy 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).
Levy County, Compared
Levy County radon figures, compared
Calculated by Radon411CDC's largest figure for Levy County rests on 23 tests over the 2008 to 2017 laboratory totals, 3 of them at or above 4 pCi/L, so each test moves its share by 4.3 points and no rank or comparison is drawn from it. Results reached as high as 4.8 pCi/L, with a middle value of 1.9 pCi/L.
Of the counties bordering it, 3 have a figure over the 2008 to 2017 laboratory totals: Marion County reported the largest share at or above 4 pCi/L, 42.9%, and Citrus County the smallest, 9.9%, with Alachua County at 35.2% between. Farther out, Hernando County (56 miles away) at 1.8%, Sumter County (58 miles away) at 25.9% and Columbia County (63 miles away) at 6.7% have figures too. Pooled across 62 Florida counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Marion County reported the highest share (42.9%) and St. Lucie County the lowest (0.0%). EPA's 1993 map puts Levy County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 85% of the county's land low radon potential.

The ground under Levy County
PredictedMost of the ground under Levy County is one class on USGS's geologic map: 84.6% of its land is low radon potential, with 12.3% moderate. The map puts 84.6% of Levy County in the area it calls Gulf/Atlantic Lowland and Central Highland and 12.3% in Highland Anomalous areas. USGS gives the first a radon index of 6, 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 |
|---|---|---|---|---|
| Gulf/Atlantic Lowland and Central Highland | sand, silt, clay, gravel | Low | 6 | 84.6% |
| Highland Anomalous areas | Phosphate deposits. | Moderate | 11 | 12.3% |
