LowEPA Zone 3

Predicted long-term basement average of 1.6 pCi/L (model estimate) across the 39 modeled ZIP codes in Fort Worth - close to the US average of 1.8, close to the Texas average of 1.5. Ranked #41 of 83 Texas cities on this site. Most of the city lies in Tarrant County (its ZIPs also reach into 3 other counties).

Test Fort Worth, TX once anyway - radon varies house to house

The predicted basement average here is 1.6 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 Worth

The typical Fort Worth home is predicted below 2 pCi/L, the lowest band. That describes the average house; the ZIP-level predictions inside the city still span 1.3 to 1.9 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 Tarrant and the 2001-2021 model agree here.

Comparable Texas cities: Wylie (1.6), Plano (1.6), Irving (1.6), Dallas (1.5).

Testing help in Texas

We link only state program pages we could verify, and Texas's did not respond when we checked, so start from the EPA state radon contacts page. If a test comes back at 4 pCi/L or higher, mitigation typically costs $800-$2,500 installed; use EPA find-a-professional and read the mitigation guide.

Fort Worth radon questions

Is radon high in Fort Worth, Texas?
Low. Averaging the model's ZIP-code predictions across Fort Worth (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 1.6 pCi/L - close to the US average of 1.8 and close to the Texas average of 1.5. That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Fort Worth ranks 41 of 83 Texas cities on this site.
Which Fort Worth ZIP codes have the highest radon?
Predictions for the 39 modeled ZIP codes in Fort Worth range from 1.3 to 1.9 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 Worth?
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 Worth's low predicted average describes the typical home, not yours.
What does EPA Radon Zone 3 mean for Fort Worth?
Fort Worth sits mainly in Tarrant 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.
