Radon is a cancer-causing natural radioactive gas that you can’t see, smell or taste. Its presence in your home, school or workplace can pose a danger to your family’s health. Radon is the leading cause of lung cancer among non-smokers. Radon is the second leading cause of lung cancer in America and claims about 20,000 lives annually. Testing your home for radon, school or workplace can be easy and inexpensive, and if your levels are elevated, they can be lowered.
