The data
Freehold, 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 Freehold, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.
Monmouth County has an EPA zone and its own CDC test figures, shown below. About 12,562 people live in Freehold.
Freehold, Counties
Each county's own EPA zone and its own published CDC figures for 2022, 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.

What it means
Freehold, Questions
EPA's Map of Radon Zones classifies counties, not cities. Monmouth County is in Zone 1 (highest predicted potential). A zone is a prediction for a whole county and never tells you the level in one home.
For 2022, the share of radon tests reported to CDC that were at or above 4 pCi/L was 9.8% in Monmouth County (9,745 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.
