Radon is a Radioactive Gas. Radon is a radioactive element that is part of the radioactive decay chain of naturally occurring uranium in soil. You canât see radon. You canât smell radon and you canât taste radon. Unlike carbon monoxide and many other home pollutants, radon's adverse health effect, lung cancer, is usually not produced immediately. Thus you may be exposed to radon for many years without ever suspecting its presence in your home. The USEPA action level for radon is 4.0 picocuries per liter of air (pCi/L).
