The data
Tampa, What is published
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 Tampa, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.
Hillsborough County has an EPA zone and its own CDC test figures, shown below. About 413,554 people live in Tampa.
Tampa, Counties
Each county's own EPA zone and its own published CDC figures for 2023, the newest period any of them has. A county without a figure for that period is shown without one, never with a figure from another year.
Hillsborough CountyZone 2Moderate predicted potential
The median reported pre-mitigation result for 2023 was 0.9 pCi/L in Hillsborough County.
CDC counts radon tests that were reported to it, not homes, and figures from few tests can swing widely from year to year. Each county’s report has its full history.

What it means
Tampa, Questions
EPA's Map of Radon Zones classifies counties, not cities. Hillsborough County is in Zone 2 (moderate predicted potential). A zone is a prediction for a whole county and never tells you the level in one home.
For 2023, the share of radon tests reported to CDC that were at or above 4 pCi/L was 7.5% in Hillsborough County (984 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.
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 Hillsborough County, the county Tampa lies in.
