EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Taylor County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

What these figures count

Only 3 tests were reported to CDC for Taylor County over 2022, 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: 2022. Measured data period: 2005 to 2022 (every CDC figure on file).

Taylor County, Compared

Taylor County radon figures, compared

Calculated by Radon411

Only 0 of 84 radon tests reported for Taylor County in 2015 reached 4 pCi/L (0.0%). 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 1.0 pCi/L.

The newest figure, in 2022, counts only 3 tests (0.0% at or above 4 pCi/L), too few to compare, so this reading uses the 84-test figure.

Across 47 Florida counties pooled together, 26.5% of tests reached that level, so Taylor County runs 26.5 points below its state. Against the national pool of 35.5%, the gap is 35.5 points lower. Its place in the state: 19th of 24 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 0.0% share point the same way here. Madison County, the one bordering county with a figure for the same period, reported 1.1%.

Below the action level, 84 tests (100.0%) came in under 2 pCi/L, against 45.3% statewide, and 0 tests (0.0%) fell between 2 and 4, against 28.2% statewide. USGS geology rates 99% of the county's land low radon potential.

The busiest year on file was 2015, with 84 tests reported; the quietest, 2021, had 1.
