Radon quick facts

••It's a radioactive gas that comes from the breakdown of uranium inside the Earth. It enters the home through cracks in floors and walls and becomes trapped inside. Radon levels then build up over time.

••It is present in nearly all air. However, according to the U.S. surgeon general, people who inhale high levels of radon are at an increased risk for developing lung cancer. Radon is the second leading cause of lung cancer in the U.S., accounting for an estimated 15,000 to 22,000 deaths per year.
