The data
Fargo, 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 Fargo, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.
Cass County has an EPA zone and its own CDC test figures, shown below. About 136,275 people live in Fargo.
Fargo, 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.
Cass CountyZone 1Highest predicted potential
The median reported pre-mitigation result for 2008 to 2017, laboratory was 4.7 pCi/L in Cass 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.

EPA's Map of Radon Zones classifies counties, not cities. Cass 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 57.5% in Cass County (862 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.
