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.

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)
