About this data

Source: Minnesota county radon testing indicators (Minnesota Department of Health). Period: 2016–2025. Published indicators: 680 properties at or above 4 pCi/L, 928 at or above 2 pCi/L, and 112 properties tested annually on average. Read the methodology →

These are voluntary and real-estate tests, not a random sample of homes, so they describe tested homes rather than every home.
