Radon tests reported for Liberty County, 2020
CDC holds 2 reported tests for Liberty County in 2020, with a median of 5.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Liberty County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Liberty County over 2020, 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. Measured data period: 2020.
Liberty County, Compared
Liberty County radon figures, compared
Calculated by Radon411CDC's largest figure for Liberty County rests on 2 tests in 2020, 1 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 10.0 pCi/L, with a middle value of 5.7 pCi/L.
Of the counties bordering it, 4 have a figure over the 2008 to 2017 laboratory totals: Leon County reported the largest share at or above 4 pCi/L, 23.3%, and Jackson County the smallest, 6.0%, with Wakulla County at 8.9% and Gadsden County at 6.3% between. Farther out, Jefferson County (61 miles away) at 6.1%, Okaloosa County (107 miles away) at 2.9% and Santa Rosa County (131 miles away) at 2.0% 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 Liberty County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.

The ground under Liberty County
PredictedUSGS's geologic map puts all of Liberty County's mapped land in one class: low radon potential. The map puts 78.8% of Liberty County in the area it calls Gulf/Atlantic Lowland and Central Highland and 21.2% in Northern Highland. USGS gives both a radon index of 6, in the low band (5 to 8).
| 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 | 78.8% |
| Northern Highland | Sand, silt, clay, gravel | Low | 6 | 21.2% |
