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 Outagamie

The typical Outagamie County 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 roughly one home in several in a moderate area will test above 4.

The 1993 EPA zone (2) and the 2001-2021 model agree for Outagamie. County figures weight each ZIP by its 2010 Census population, so they describe where people live rather than empty land.

Comparable Wisconsin counties: Clark County (2.3), Barron County (2.4), Columbia County (2.3), Eau Claire County (2.3). The state's highest is Lafayette County at 3.4 pCi/L.
