Radon testing in Ames & Story County
Testing in Ames and Boone is routine in a Zone 1 state, and the most common local trigger is a basement-finishing project. That is the right instinct — the number you want is for the space you are about to start living in.
Story and Boone counties sit on the Des Moines Lobe, the youngest glacial landscape in Iowa — Wisconsinan till laid down roughly twelve to fourteen thousand years ago, flat, poorly drained, and pocked with the closed depressions that once made this prairie-pothole country. The Des Moines River has cut a deep valley through Boone County, exposing the section and creating a very different setting on the valley slopes.
How testing works in this market
Place the detector on the lowest lived-in level, or on the basement floor if you are about to finish it, twenty inches up and away from exterior walls, drafts, and the sump. Keep the house closed twelve hours before a short-term test and throughout. For occupied student rentals, switch instruments rather than bending the protocol: a ninety-day alpha-track detector averages across ordinary living and produces a defensible figure where a two-day test in a shared house does not. Record the exact placement for later comparison. Ames pairs a large student-rental sector near Iowa State with owner-occupied neighborhoods of postwar ranches and 1990s-forward subdivision colonials on poured basements. Nevada, Huxley, Gilbert, and Story City are small-town Iowa with older cellars and newer infill. Boone is an older railroad town with a deep stock of 1890s–1930s housing on block and stone foundations.
When to test, and when to retest
A first result is a starting point, not a verdict. EPA's guidance is to confirm a short-term result before spending money on a system, to test the lowest lived-in level, and to keep the house under closed-building conditions throughout. A measurement done for pay in Iowa calls for an Iowa measurement certification; a do-it-yourself kit you buy and mail in yourself does not, and for a first look at your own house it is a legitimate place to start. Central Iowa winters give strong stack effect and reliable closed-house conditions from December through March. The late-summer rental turnover window is the practical time to test and mitigate investment property, when units are vacant and closed-building conditions are actually enforceable.
Testing inside a home sale
Iowa sellers disclose known radon information on the state residential disclosure form; nothing requires testing or mitigation. Story County’s large student-rental market means many properties changing hands have never been measured, so buyers should assume no data exists and order their own test.

Radon Testing questions in Ames & Story County
Does an unfinished basement need testing if nobody goes down there?
Test it if you might ever finish it, because that is the number that will matter when you do. If it is genuinely just utilities, also test the lowest floor you occupy, since that reading describes your current exposure. Many Story County homeowners test both levels at once — the cost of a second detector is trivial next to the cost of guessing.
What do homeowners in Ames & Story County get wrong about testing?
Landlord questions dominate near campus — how to test an occupied unit, whether a system survives tenants, what a verified number does at listing. Owner-occupants ask about finishing basements, which is the most common trigger for a first test here. Boone homeowners ask whether a stone foundation can hold suction; it can, with sealing in the design.
Can I use a hardware-store kit instead of hiring someone?
For your own information, yes — a do-it-yourself short-term kit placed on the lowest lived-in level of a home in Ames & Story County, under closed-building conditions, is a real measurement, and EPA treats it as a legitimate first step. For a real-estate transaction the parties usually want an independent measurement by someone holding an Iowa measurement certification, because a self-reported number from an interested party is easy for the other side to challenge.
