Radon is an invisible, odorless gas that can seep into your home through cracks in floors, walls and foundations. You can't see radon. You can't smell it or taste it. But it may be a problem in your home.
Radon comes from the natural breakdown of uranium in soil, rock and water. Radon gas escapes from the ground into the air outside. When radon mixes with the air outside, it’s not a problem: the air outside dilutes the amount of radon. But when radon seeps into a closed-in space like a house, it can be harmful. The radon gas can become trapped inside. You and your family can breathe in high levels of radon without knowing it.
