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 Salem, 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 181,779 people live in Salem.

Salem, Questions
Questions about radon in Salem
What radon zone is Salem in?
EPA's Map of Radon Zones classifies counties, not cities. Marion County and Polk County are 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 Salem's counties?
For 2023, the share of radon tests reported to CDC that were at or above 4 pCi/L was 16.0% in Marion County (194 tests) and 10.1% in Polk County (79 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 Salem?
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 Marion County and Polk County, the counties Salem lies in.
