EPA puts Manatee County in Zone 3, its lowest radon zone, and most reported tests there come back low, though 11.0% of 263 (2023) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Manatee County, Compared
Manatee County reports fewer high tests than Florida overall. 11.0% of its 263 tests in 2023 were at or above 4 pCi/L. That is 7.5 points below the 18.5% pooled from 49 Florida counties.
Ordered from highest share down, it comes 12th of 30 Florida counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 33.4%; Manatee County sits 22.4 points below it.
Next door, the shares run from 7.5% in Hillsborough County to 12.3% in Sarasota County, with Hillsborough County below Manatee County. Zone 3 on EPA's map (predicted average under 2 pCi/L) and a 11.0% share point the same way here.
Half the tests came in under 1.5 pCi/L and half over it; the single highest reached 13.3 pCi/L. The rest split 65.8% under 2 pCi/L and 23.2% from 2 to 4 (Florida: 57.3% and 24.2%). Year by year, 2014 opened at 32.4% and 2023 closed at 11.0% (down 21.4 points), with 2014 the high at 32.4%.
The busiest year on file was 2022, with 1,263 tests reported; the quietest, 2016, had 22.

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 | 86.6% |
| Highland Anomalous areas | Phosphate deposits. | Moderate | 11 | 6.9% |
