Is radon high in Fort Pierce, Florida?

Low.

That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Fort Pierce ranks 63 of 89 Florida cities on this site.

Which Fort Pierce ZIP codes have the highest radon?

Predictions for the 7 modeled ZIP codes in Fort Pierce range from 1.1 to 1.4 pCi/L in the basement. 0% of them are predicted at or above 4 pCi/L and 0% at or above 2. The city is fairly uniform, so the city-wide number is a reasonable guide for any neighborhood.

Should I test for radon in Fort Pierce?

Yes, once. The EPA recommends testing every home regardless of area. A short-term kit costs little and settles the question for your house; Fort Pierce's low predicted average describes the typical home, not yours.

Fort Pierce sits mainly in St. Lucie County, which the EPA classifies as Zone 3 - low potential (< 2 pCi/L). The zone map dates from 1993 and covers whole counties. The 2001-2021 model agrees with the zone for the city. Neither replaces a test of your own home.

Test Fort Pierce, FL once anyway - radon varies house to house

The predicted basement average here is 1.2 pCi/L, below the EPA's 2 pCi/L "consider fixing" threshold. That's good news for the area - but the EPA still recommends every home be tested, because foundation cracks, soil pockets and ventilation make one house very different from its neighbor. One inexpensive kit settles it.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

What this means for Fort Pierce

The typical Fort Pierce home is predicted below 2 pCi/L, the lowest band. That describes the average house; the ZIP-level predictions inside the city still span 1.1 to 1.4 pCi/L.

The city figure is not a separate estimate: it is the mean of the model's ZIP-code predictions, weighted by the share of the city's land in each ZIP (Census 2020 ZCTA-to-place relationship file). The 1993 EPA zone (3) for St. Lucie and the 2001-2021 model agree here.

Comparable Florida cities: Coconut Creek (1.2), Sarasota (1.2), Winter Haven (1.2), Orlando (1.2).
