Radon comes from the natural radioactive breakdown of uranium in soil, rock, and water. It is an invisible, odorless, tasteless, cancer-causing gas that enters buildings through the numerous cracks, holes, and pipes in the foundation. It can also enter a building from well water.
Radon can be found in any building, but homes are the most concerning since that’s where families spend the most time.
