Is radon high in Coshocton County, Ohio?

High. The model predicts a long-term basement average of 4.2 pCi/L in Coshocton County (about 2.3× the US average of 1.8 and about 1.5× the Ohio average of 2.8). That is at or above the EPA action level of 4 pCi/L, so the typical home here would qualify for mitigation. Ranked 9 of 88 Ohio counties.

Should I test for radon in Coshocton County?

Yes, soon. With a predicted average of 4.2 pCi/L and at least one ZIP predicted at 4.4, many homes in Coshocton County will test above the 4 pCi/L action level. Use a short-term kit first; if it reads 2 or higher, confirm with a long-term test or continuous monitor before deciding on mitigation.

What does EPA Radon Zone 1 mean for Coshocton County?

Zone 1 - highest potential (predicted average > 4 pCi/L). The zone map dates from 1993 and classifies whole counties. The 2001-2021 model agrees with the zone here. 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.
