Radon! What’s up with this colorless, odorless, tasteless gas? It causes Lung Cancer! Since October 2010, siblings Christina and Eric Bear are on a mission to spread awareness about radon. Radon can change the DNA in your lungs and exposure over many years can cause lung cancer. Colorado is a high radon region. The U. S. Surgeon General estimates over 21,000 deaths in the U. S. related to radon yearly. This is preventable! Visit the Resources page to find out more about radon and what you can do to keep yourself safe.
