Radon is an invisible, tasteless, and odorless radioactive gas that seeps into homes from underground. It is caused by the decay of uranium, which is plentiful in the Rocky Mountain states and is widely found in trace amounts in rocks and soil. Uranium first decomposes to radium and then into radon.
Fifty-two of Colorado’s 64 counties are at high risk for radon gas, and Park County is one of the hot zones, known as “zone 1,” in Colorado.
Radon, which occurs naturally from the decay of uranium, is the number-one cause of lung cancer among non-smokers in America, with cigarette smoking being the number-one cause of lung cancer among the smoking population, according to U.S. Surgeon General.
Radon is responsible for about 21,000 lung cancer deaths every year and, among those, approximately 2,900 occur among people who have never smoked, according to the U.S. Environmental Protection Agency.
