Note: Radon is a gas that has no odor, color, or taste. It is produced naturally by the breakdown of uranium in the ground. Radon can enter your home through cracks in the foundation or other openings. Once inside, it can build up to high levels and become a health hazard. Radon is the leading cause of lung cancer in non-smokers. If you live in an area with high radon levels, you should have your home tested for radon. If your home has high levels of radon, there are ways to reduce the amount of radon in your home.
