Is radon high in ZIP 26003?

Moderate. The model's predicted long-term basement average for ZIP 26003 is 2.5 pCi/L (SD 0.08), with above-ground floors at 1.8 pCi/L. That is about 1.2× the average US ZIP code (2.2) and close to the Ohio County average of 2.6. It ranks 2 of 3 ZIPs in the county.

Do I need to test my home in 26003?

Yes. 26003's predicted average falls in the EPA's 2-4 pCi/L "consider fixing" band, and a meaningful share of individual homes in such areas test above 4. Test with a short-term kit and confirm anything at 2 or higher with a long-term test.

What EPA radon zone is ZIP 26003 in?

ZIP 26003 lies mostly in Ohio County, which the EPA classifies as Radon Zone 1 (highest potential (predicted average > 4 pCi/L)). Zones are county-wide and date from 1993; the ZIP-level prediction above is from a 2001-2021 model built on millions of tests.

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.
