Radon is a naturally occurring radioactive gas responsible for more than 500 lung cancer deaths in Colorado each year. The colorless, odorless, tasteless gas can enter homes through cracks in the foundation or other openings and can accumulate unless properly mitigated.

Gov. John Hickenlooper recently encouraged residents to test their homes for radon to protect their health.

Long-term radon exposure is the leading cause of lung cancer in nonsmokers and the second-leading cause of lung cancer in smokers.

The U.S. Environmental Protection Agency recommends installing mitigation systems in any home with a level of 4 picocuries or more per liter of indoor air. If your home already has a mitigation system, you still should test yearly to ensure the system is working properly.
