The Radon Picture in Polk County
In tests reported to the CDC Tracking Network from 2008 through 2017, the average Polk County home measured 7.3 pCi/L before any mitigation, 1.8 times the EPA action level of 4. That ranks 63rd among Iowa's 99 counties. Iowa as a whole averages 8.5 pCi/L and the United States 1.3, and every county in the state, Polk included, is EPA Zone 1.
A county average is a statement about odds, not about your house. Iowa HHS notes that two homes on the same street routinely test very differently, because what matters is the soil under the footprint and how easily gas moves into that particular foundation. Our guide to why Iowa radon runs so high explains the geology; the county ranking shows where Polk sits against the other 98.
Whatever the number, the fix is the same one we install across central Iowa: a sealed suction point, an exterior fan, a vent above the roofline, and a clearance test, guaranteed below 2.7 pCi/L. See what goes in on our radon mitigation in Des Moines page, or book a certified test first.

Free radon test kit
Yes. Polk County homes qualify for a free Iowa radon test kit.
Iowa HHS and the American Lung Association offer one free short-term radon test kit per household in Polk County while supplies last. Order it through the Lung Association's form, run it in the lowest lived-in level for the days it specifies, and mail it to the lab.
Request a free kit (American Lung Association) →A free kit is a mailed charcoal test: results take a couple of weeks, one kit can miss a high reading, and it is not accepted for a real-estate sale. If it comes back at 4.0 pCi/L or higher, the next step is a certified 48-to-72-hour monitor test with same-day results, then a same-day mitigation quote.

How does Polk County compare to the rest of Iowa for radon?
Polk County's average of 7.3 pCi/L ranks 63rd of 99 counties in the CDC's 2008 to 2017 data. Iowa as a whole averages 8.5 pCi/L, and 94 of 99 counties average above the EPA action level of 4. Every county in Iowa is EPA Zone 1.
Can I get a free radon test kit in Polk County?
Yes. Polk County households can request one free short-term radon test kit through the Iowa HHS and American Lung Association free kit program, while supplies last. A kit is a good first look, but results take weeks and it is not accepted for a home sale. A certified 48-to-72-hour monitor test gives same-day results, and any reading at 4.0 pCi/L or above should be confirmed that way before mitigation.
Does the county average tell me whether my home has radon?
No. Iowa HHS notes that radon varies considerably from house to house, even between neighbors, because it depends on the soil under the footprint and how easily gas moves into that particular house. The county figure tells you the odds are high; a 48-to-72-hour certified test tells you the answer.
