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 Westerville, 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 38,165 people live in Westerville.

What it means
Westerville, Questions
Questions about radon in Westerville
What radon zone is Westerville in?
EPA's Map of Radon Zones classifies counties, not cities. Delaware 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 Westerville'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) 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 Westerville?
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 and Franklin County, the counties Westerville lies in.
