The data
Ames, What is published
Radon data is published by county, not by city
Radon data is published by county, not by city. EPA assigns radon zones to counties, and CDC publishes radon test figures by county. Neither publishes a figure for Ames, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.
Story County has an EPA zone and its own CDC test figures, shown below. About 68,220 people live in Ames.
Ames, Counties
Each county's own EPA zone and its own published CDC figures for 2008 to 2017, laboratory, the newest period any of them has. A county without a figure for that period is shown without one, never with a figure from another year.
Story CountyZone 1Highest predicted potential
The median reported pre-mitigation result for 2008 to 2017, laboratory was 5.0 pCi/L in Story County.
CDC counts radon tests that were reported to it, not homes, and figures from few tests can swing widely from year to year. Each county’s report has its full history.

Iowa’s radon program approves applications for persons who wish to become certified to perform radon testing or credentialed to perform mitigation and laboratories that provide radon testing devices and analytical services.
However, per Iowa Code chapters 543B.9 and 543B.18 and Iowa Administrative Code 193E Chapter 14 administered by the Iowa Real Estate Commission, a seller must disclose any known tests for the presence of radon and if yes, provide the date of last report and the result(s).
What it means
Ames, Questions
EPA's Map of Radon Zones classifies counties, not cities. Story County is in Zone 1 (highest predicted potential). A zone is a prediction for a whole county and never tells you the level in one home.
For 2008 to 2017, laboratory, the share of radon tests reported to CDC that were at or above 4 pCi/L was 59.9% in Story County (2,568 tests). Each is that county's own figure, counting tests reported to CDC, not homes. Radon411 does not average or combine them into a figure for the city.
Yes. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L. How to test a home.
The answers use the published figures of Story County, the county Ames lies in.
