Radon Aware Colorado Protects Residents from Radon Exposure

Radon Health Risks

Public health agencies across Colorado created the Public Health Radon Aware Colorado initiative to reduce exposure to radioactive radon gas and the associated risk of lung cancer.

In Colorado, 50% of homes have unhealthy radon levels, equivalent to every person in residence having 200 chest X-rays every year. This compares with only 6% of homes having unhealthy radon levels across the rest of the country.

Radon is the leading cause of lung cancer deaths among nonsmokers in the U.S. and claims the lives of about 21,000 Americans each year. Radon-induced lung cancer is the eighth leading cause of cancer death in the U.S., and as many as 500 Coloradoans die from radon-induced lung cancer every year.

Action Steps

It takes actions by all of us to reduce radon risk and save lives. Below are actions real estate and building industry professionals, homebuyers, rental property owners, policy-makers, and local public health agencies can take to protect children, families, and their communities:
