What Is Radon?
Radon is a radioactive gas that comes from the natural breakdown of uranium in the soil, rock, and water. Radon rises from the soil underneath homes and gets into the air you breathe. Radon is invisible, tasteless, and odorless. In Colorado, about half the homes have elevated radon levels above the EPA’s recommended action level of 4 picocuries per liter (pCi/L). According to the CDC, Surgeon General, and the EPA, Radon is highly radioactive and is the second leading cause of cancer after smoking. It’s estimated to cause about 21,000 lung cancer deaths per year in the United States.
