Radon Testing in Alleman

Radon Testing in Alleman, Polk County, by Closer Look Inspectors. Alleman is the most recently incorporated city in Polk County, built around an old interurban stop.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Iowa, where Iowa HHS reports 71.6 percent of homes above the action level — the largest percentage of any state.

Local housing

Homes in Alleman.

Alleman housing runs to a mix of older stock along the old interurban line and newer homes built since the 1973 incorporation, across the town on the old Fort Dodge, Des Moines and Southern interurban alignment, and the Polk County acreages around it, on the northern Polk County edge of the Des Moines Lobe — younger, flatter till that drains slowly — and that mix shapes what a radon testing here needs to find.

Local conditions in Alleman

No Iowa law requires a home inspection before a sale — the one mandatory time-of-transfer inspection covers private septic systems (Iowa Code 455B.172) — which makes an independent inspection the only thorough, buyer-side read on an Alleman home. Alleman sits in Polk County, and every Iowa county is EPA Radon Zone 1. Iowa HHS reports Iowa has the largest percentage of homes above the 4.0 pCi/L action level of any state — 71.6 percent in the Iowa Radon Survey — and the Iowa seller disclosure form asks for any known radon test results. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Iowa leaves frost depth to the local building code rather than one statewide number, and the annual freeze-thaw cycle drives the settlement cracks and ice-dam wear that Alleman-area homes face.

Questions

Common questions.

Is radon really a concern in Iowa?
Yes. The Iowa Department of Natural Resources reports that more than two in five Iowa homes have radon levels that pose a significant health risk, and finished basements are where it concentrates.
How long does the test run?
A 48-hour minimum under closed-house conditions; the result is delivered with your inspection report.
Alleman only incorporated in 1973 — is the housing all modern?
No, and that is the useful thing to know. Alleman is the most recently incorporated city in Polk County, incorporated May 18, 1973, but it existed long before that as an interurban stop on the Fort Dodge, Des Moines and Southern from 1906, with commuter service ending in 1928. So the stock runs from early-1900s frame homes through recent construction, and the two need different reads. Drainage matters as well: this is Des Moines Lobe till at the northern edge of Polk County, younger and flatter than the drift plain, and it holds water against foundations.
