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 Columbus, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.
Each county has its own CDC test figures, shown below side by side. About 938,396 people live in Columbus.

What it means
Columbus, Questions
Questions about radon in Columbus
What radon zone is Columbus in?
EPA's Map of Radon Zones classifies counties, not cities. Delaware County, Fairfield County and Franklin County are 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 Columbus's counties?
For 2008 to 2017, laboratory, the share of radon tests reported to CDC that were at or above 4 pCi/L was 72.2% in Delaware County (3,730 tests), 76.8% in Fairfield County (1,175 tests) and 71.9% in Franklin County (16,142 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 Columbus?
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 Delaware County, Fairfield County and Franklin County, the counties Columbus lies in.
