Is radon high in Beavercreek, Ohio?

Moderate. Averaging the model's ZIP-code predictions across Beavercreek (weighted by how much of the city each ZIP covers) gives a long-term basement mean of 3.1 pCi/L - about 1.7× the US average of 1.8 and close to the Ohio average of 2.8. That is in the 2-4 pCi/L range where the EPA says to consider fixing. Beavercreek ranks 8 of 27 Ohio cities on this site.

Which Beavercreek ZIP codes have the highest radon?

Predictions for the 7 modeled ZIP codes in Beavercreek range from 2.3 to 4.4 pCi/L in the basement. 14% of them are predicted at or above 4 pCi/L and 100% at or above 2. That spread is why the ZIP table below matters more than the city-wide number.

Should I test for radon in Beavercreek?

Yes, soon. With a predicted basement average of 3.1 pCi/L and ZIPs predicted as high as 4.4, a meaningful share of Beavercreek 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 1 mean for Beavercreek?

Beavercreek sits mainly in Greene County, which the EPA classifies as Zone 1 - highest potential (predicted average > 4 pCi/L). The zone map dates from 1993 and covers whole counties. The newer model's city average of 3.1 pCi/L does not line up with Zone 1, which is common - the EPA itself says high-radon homes exist in every zone. Neither replaces a test of your own home.

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 Beavercreek

The typical Beavercreek 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). Note that the EPA classifies Greene County as Zone 1 while the newer model predicts 3.1 pCi/L for Beavercreek; where they disagree, we grade on the model but show both.

Comparable Ohio cities: Fairfield (3.1), Middletown (2.9), Dayton (2.9), Kettering (2.8).
