Do I really need to test my home for Radon?
Radon is a radioactive gas that has been found in homes all over the United States. It comes from the natural breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Radon can also enter your home through well water. Your home can then trap radon inside. According to the Surgeon General, "Indoor radon is the second leading cause of lung cancer in the United States".
Any home can have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements. In fact, you and your family are most likely to get your greatest radiation exposure at home. That is where you spend most of your time.
Radon is measured in picocuries per liter (pCi/L) of air measured. Approximately 50% of the homes I test in Colorado have elevated radon levels above 4.0 pCi/L. If high radon levels are found in your home, a mitigation system can be installed to reduce these levels.
This map is not intended to be used to determine if a home in a given zone should be tested for radon. It merely shows us the potential for high radon levels within the state of Colorado.
