Radon Test Kit

 

Radon is an odorless radioactive gas that results from the breakdown of uranium in soil, rock and water. You cannot see or smell radon, but it can become a health hazard when it accumulates indoors.  It can enter your home through cracks and openings in the foundation floor and walls.

The only way to know if you have high levels of radon is to test!
