Radon Facts

  • Radon causes lung cancer.
  • Radon is a naturally occurring radioactive gas that comes up out of the ground.
  • Radon enters a home from the ground under a house through cracks or openings in the foundation, slab or crawl space ground. When this occurs, radon can accumulate in dangerous levels.
  • Radon is a Class A human carcinogen – the U.S. EPA and Surgeon General estimate radon is responsible for more than 25,000 annual lung cancer deaths among non-smokers. Radon is a part of mother nature(naturally occurring) and can be present in any house.
