What these figures count
Only 10 tests were reported to CDC for Okaloosa 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).
Okaloosa County, Compared
Okaloosa County radon figures, compared
Calculated by Radon411Only 3 of 180 radon tests reported for Okaloosa County in 2022 reached 4 pCi/L (1.7%). The median result, 0.4 pCi/L, sits below 2, well under EPA's 4 pCi/L action level, and the top reported result was 4.0 pCi/L.
The newest figure, in 2023, counts only 10 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 180-test figure.
Across 54 Florida counties pooled together, 22.8% of tests reached that level, so Okaloosa County runs 21.1 points below its state. Against the national pool of 23.9%, the gap is 22.2 points lower. Its place in the state: 24th of 40 Florida counties with 30 or more tests for the same period.
Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 1.7% share point the same way here. Santa Rosa County, the one bordering county with a figure for the same period, reported 2.2%.
Below the action level, 171 tests (95.0%) came in under 2 pCi/L, against 52.6% statewide, and 6 tests (3.3%) fell between 2 and 4, against 24.6% statewide. USGS geology rates 94% of the county's land low radon potential.
The busiest year on file was 2022, with 180 tests reported; the quietest, 2020, had 1.
