Why Illinois Has Some of the Highest Radon Levels in the U.S.

Contributing Factors:

Glacial soil composition
Limestone bedrock
Seasonal pressure differentials (stack effect)
Modern airtight construction practices

What is Radon?

Radon is a radioactive noble gas formed from the decay of uranium in soil. It infiltrates structures through: Foundation cracks, Sump pits, Utility penetrations, Crawlspaces and slab joints

Once inside, radon accumulates—especially in basements and lower levels.
