Measured: tests reported to CDC
CDC holds 3 reported tests for Glades County over the 2008 to 2017 laboratory totals, with a median of 1.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Glades County beside the counties around it is how this page reads it.
Only 3 tests were reported to CDC for Glades County over 2008 to 2017 (laboratory totals), 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: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Glades County, Compared
CDC's largest figure for Glades County rests on 3 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 2.4 pCi/L, with a middle value of 1.7 pCi/L.
Of the counties bordering it, 5 have a figure over the 2008 to 2017 laboratory totals: Charlotte County reported the largest share at or above 4 pCi/L, 25.3%, and DeSoto County the smallest, 4.4%, with Lee County at 25.1%, Martin County at 10.7% and Palm Beach County at 7.8% between. Farther out, St. Lucie County (53 miles away) at 0.0%, Collier County (59 miles away) at 25.9% and Indian River County (62 miles away) at 2.5% 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 Glades 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.

Glades County, Geology
USGS's geologic map puts all of Glades County's mapped land in one class: low radon potential. All of it lies in the area the map calls Gulf/Atlantic Lowland and Central Highland, to which USGS gives 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 | 100% |

Across Florida 7.1% of the land is rated moderate; none of Glades County's is. None of the 8 counties that border it has any moderate-potential ground either.
