What is radon?

Radon is a naturally occurring radioactive gas that causes hundreds of lung cancer deaths each year. The colorless, odorless, tasteless gas enters homes through cracks in a building’s foundation or other openings and can accumulate unless properly mitigated. Long-term radon exposure is the leading cause of lung cancer in nonsmokers and the second-leading cause of lung cancer in smokers. In Colorado, approximately half the homes have radon levels higher than the EPA recommended action level of 4 picoCuries per liter of indoor air.
