Is radon high in Lubbock, Texas?

Moderate. Averaging the model's ZIP-code predictions across Lubbock (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 2.0 pCi/L - close to the US average of 1.8 and about 1.3× the Texas average of 1.5. That is in the 2-4 pCi/L range where the EPA says to consider fixing. Lubbock ranks 2 of 83 Texas cities on this site.

Which Lubbock ZIP codes have the highest radon?

Predictions for the 14 modeled ZIP codes in Lubbock range from 1.7 to 2.2 pCi/L in the basement. 0% of them are predicted at or above 4 pCi/L and 43% 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 Lubbock?

Yes, soon. With a predicted basement average of 2.0 pCi/L, a meaningful share of Lubbock homes will test above the 4 pCi/L action level. Start with a short-term kit; if it reads 2 or higher, confirm with a long-term test or a continuous monitor before paying for mitigation.

What does EPA Radon Zone 2 mean for Lubbock?

Lubbock sits mainly in Lubbock County, which the EPA classifies as Zone 2 - moderate potential (2-4 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.

ModerateEPA Zone 2

Predicted long-term basement average of 2.0 pCi/L (model estimate) across the 14 modeled ZIP codes in Lubbock - close to the US average of 1.8, about 1.3× the Texas average of 1.5. Ranked #2 of 83 Texas cities on this site. Most of the city lies in Lubbock County (its ZIPs also reach into 1 other county).

Test Lubbock, TX - the EPA says "consider fixing" in this range

The predicted basement average here is 2.0 pCi/L, in the 2-4 pCi/L band where the EPA recommends considering mitigation. Plenty of individual homes in a moderate area test above 4. Start with a short-term test; if it comes back at 2 or higher, follow up with a long-term test or a continuous monitor.

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 Lubbock

The typical Lubbock home is predicted in the 2-4 pCi/L band. The EPA's guidance for this range is to consider fixing, because there is no known safe level and a meaningful minority of homes in a moderate area will test above 4.

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 (2) for Lubbock and the 2001-2021 model agree here.

Comparable Texas cities: El Paso (2.0), Burleson (1.9), Sherman (1.9), Leander (1.9).

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.
