pCi/L (picocuries per liter) is the unit radon is measured in. EPA recommends fixing a home at 4 pCi/L or above, its action level.

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 St. Cloud, 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 72,647 people live in St. Cloud.

Questions about radon in St. Cloud
What radon zone is St. Cloud in?
EPA's Map of Radon Zones classifies counties, not cities. Sherburne County and Stearns County are in Zone 1 (highest predicted potential); Benton County is in Zone 2 (moderate predicted potential). The counties St. Cloud lies in do not share one zone, so no single zone is given for St. Cloud. 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 St. Cloud's counties?
For 2023, the share of radon tests reported to CDC that were at or above 4 pCi/L was 23.3% in Benton County (43 tests), 21.7% in Sherburne County (351 tests) and 46.7% in Stearns County (366 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 St. Cloud?
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 Benton County, Sherburne County and Stearns County, the counties St. Cloud lies in.
