Is radon high in Spring Hill, Florida?

Low. Averaging the model's ZIP-code predictions across Spring Hill (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 1.2 pCi/L - about 32% below the US average of 1.8 and close to the Florida average of 1.3. That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Spring Hill ranks 48 of 89 Florida cities on this site.

Which Spring Hill ZIP codes have the highest radon?

Predictions for the 5 modeled ZIP codes in Spring Hill range from 1.1 to 1.5 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 Spring Hill?

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

What does EPA Radon Zone 3 mean for Spring Hill?

Spring Hill sits mainly in Hernando 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.

LowEPA Zone 3

Predicted long-term basement average of 1.2 pCi/L (model estimate) across the 5 modeled ZIP codes in Spring Hill - about 32% below the US average of 1.8, close to the Florida average of 1.3. Ranked #48 of 89 Florida cities on this site. Most of the census-designated place lies in Hernando County.

Test Spring Hill, 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 Spring Hill

The typical Spring Hill 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 1.5 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 census-designated place's land in each ZIP (Census 2020 ZCTA-to-place relationship file). The 1993 EPA zone (3) for Hernando and the 2001-2021 model agree here.

Comparable Florida cities: Ocoee (1.2), Ormond Beach (1.2), Brandon (1.3), Boca Raton (1.2).
