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.
