WHAT IS RADON?
Radon is a naturally occurring radioactive gas that you canít see, taste or smell. It is produced by the breakdown of uranium in soil, rock and water. All rocks contain some uranium, although most contain just a small amount. Certain types of rock, including granites, dark shales, light-colored volcanic rocks, sedimentary rocks containing phosphate, and metamorphic rocks derived from these rocks, have higher than average uranium contents.
High levels of Radon have been found in all 50 states.
