Radon Levels Impact to Smokers and Non-Smokers

Exposure to high levels of radon elevates your risk of lung cancer. Unfortunately, all counties in Colorado have been marked as high-risk zones by the EPA. But, worry not. Here you will find tips to help you reduce your risk to radon exposure.

Health Effects of Radon

Health Effects of RadonExposure to high levels of radon is the second cause of lung cancer and the primary cause of lung cancer among non-smokers. This odorless gas is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among non-smokers. In January 2005, Dr. Richard H. Carmona, then U.S. Surgeon General, issued a national health advisory on radon.

Lung cancer kills thousands of North Americans every year. Radon is one of the leading causes – behind smoking – of lung cancer. Despite the fact that lung cancer can be treated, the survival rate is one of the lowest for those with cancer. Usually, from the time it is diagnosed, between eleven and fifteen percent of those that suffer cancer will live beyond five years.

Smoking is the number one cause of lung cancer, and it causes an estimated 160,000 cancer deaths in the United States every year. In 1964, Dr. Luther L. Terry unveiled the first warning on the link between smoking and lung cancer. A person who smokes and is also exposed to radon has a much higher risk of lung cancer.
