Raleigh, What is published
What is published for Raleigh
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 Raleigh, 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 506,306 people live in Raleigh.

What it means
Raleigh, Questions
Questions about radon in Raleigh
What radon zone is Raleigh in?
EPA's Map of Radon Zones classifies counties, not cities. Wake County is in Zone 2 (moderate predicted potential); Durham County is in Zone 3 (lower predicted potential). The counties Raleigh lies in do not share one zone, so no single zone is given for Raleigh. 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 Raleigh's counties?
For 2022, the share of radon tests reported to CDC that were at or above 4 pCi/L was 0.0% in Durham County (10 tests) and 2.3% in Wake County (88 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 Raleigh?
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 Durham County and Wake County, the counties Raleigh lies in.
