Is radon high in ZIP 68445?

High. The model's predicted long-term basement average for ZIP 68445 is 4.8 pCi/L (SD 0.05), with above-ground floors at 2.5 pCi/L. That is about 2.2× the average US ZIP code (2.2) and close to the Saline County average of 4.5. It ranks 5 of 7 ZIPs in the county.

Do I need to test my home in 68445?

Yes, now. A predicted average at or above the EPA action level of 4 pCi/L means most homes in 68445 would qualify for mitigation. Use a short-term charcoal kit or a continuous monitor; if the result is 4 or higher, get bids for a mitigation system (typically $800-$2,500).

What EPA radon zone is ZIP 68445 in?

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.
