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.
Health Risks: Why is Radon a Serious Threat?
-
#1 cause of lung cancer among non-smokers
-
Linked to thousands of U.S. deaths annually
-
Long-term exposure significantly increases risk
There are no immediate symptoms, making testing critical.

Radon Levels Explained
Radioactivity (and radon gas) results are measured in units of picocuries (pCi) [per liter of air] in the United States versus the International System of Units (SI), the Becquerel (Bq). A picocurie is a unit of radioactivity that is equivalent to one trillionth of a curie. In Perspective, one cure measures the rate of radioactive decay, specifically 3.7 x 10^10 disintegrations per second.
What is an Action Level?
The EPA recommends fixing homes when radon levels reach 4 pCi/L (150 Bq/m³) or higher. Since no known level of radon exposure is considered safe, the EPA also urges Americans to consider taking action when levels fall between 2 and 4 pCi/L (75–150 Bq/m³). (epa.gov)
