Information:

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

Douglas County has an EPA zone and its own CDC test figures, shown below. About 488,797 people live in Omaha.

What it means

Omaha, Questions

Questions about radon in Omaha

What radon zone is Omaha in?

EPA's Map of Radon Zones classifies counties, not cities. Douglas 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.

How many radon tests come back high in Omaha's counties?

For 2023, the share of radon tests reported to CDC that were at or above 4 pCi/L was 38.7% in Douglas County (2,754 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.

Should I test my home in Omaha?

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.
