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 Aberdeen, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.

Brown County has an EPA zone and its own CDC test figures, shown below. About 27,961 people live in Aberdeen.
