​What Is Radon? (Scientific Overview)

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. Radon may be detected in elevated levels in up to the third level of a dwelling.
