Radon Testing in Arion

Radon Testing in Arion, Crawford County, by Closer Look Inspectors. Arion is a small Boyer River town whose population peaked in 1930 and has been thinning since, and we calibrate every visit to that.

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.

Tuned to Arion.

Arion housing runs to early-1900s and 1920s-era houses from the years the town peaked at 269 people, mixed with a few mid-century homes and much less new building, across the small town grid along the Boyer River and the farmsteads and acreages of the Boyer Valley around it, on the valley of the Boyer River in the loess-mantled Southern Iowa Drift Plain — and that mix shapes what a radon testing here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Arion

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 Arion home. Arion sits in Crawford 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 we calibrate every Arion visit to find.

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.
How does the Boyer River shape what an inspector checks in Arion?
Arion sits along the Boyer River, and river-valley lots can see high groundwater and wet basements after heavy rain, especially on the lower parts of a small town. We look for staining and efflorescence on basement walls, sump pump condition and discharge, grading and downspouts, and old crawlspace moisture. The town has thinned from 269 people in 1930 to 97 in 2020, so some houses have gone long stretches without regular upkeep. We also date the wiring, plumbing, heating and roof, and check on private wells and septic systems.
