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

Mecklenburg County has an EPA zone and its own CDC test figures, shown below. About 964,784 people live in Charlotte.

Questions about radon in Charlotte

What radon zone is Charlotte in?

EPA's Map of Radon Zones classifies counties, not cities. Mecklenburg County is in Zone 3 (lower 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 Charlotte's counties?

For 2022, the share of radon tests reported to CDC that were at or above 4 pCi/L was 0.0% in Mecklenburg County (17 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 Charlotte?

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.
