Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in the soil. Radon has no color, odor, or taste. Radon is the second leading cause of lung cancer in the United States and half of Colorado homes have radon levels higher than the U.S. EPA recommended action level of 4 pCi/L. There are many pathways that radon can enter into your home putting those in your home at risk for possible radon exposure.
