You’re viewing recent indoor radon levels measured by homeowners using Airthings* smart radon monitors.
While geology plays an important role, factors like building type, weather, and foundation gaps also impact radon risk levels.
This map does not predict radon risk for your home. In fact, it demonstrates that homes in the same region are reporting varying levels of indoor radon.
Q: Does this map show if my home has radon?
A: No. The map shows general readings, but radon levels vary widely between homes—even next door.
Q: Why are radon levels different in the same area?
A: Differences in soil, construction, and ventilation can cause radon levels to vary significantly between homes.
Q: Should I test my home even if my area shows low radon?
A: Yes. Every home should be tested because radon cannot be predicted by location alone.
