Radon is a naturally occurring, radioactive gas that is invisible, odorless, and tasteless. It is produced by the decay of uranium in soil, rock, and water, and it can seep into any type of building—homes, offices, and schools—through cracks in the foundation, construction joints, and other openings.
Prolonged exposure to elevated radon levels is the second leading cause of lung cancer in the United States and the number one cause among non-smokers. Since you can’t see or smell it, the only way to know if your home has a dangerous level of radon is to perform a professional test.
