Radon can be found all over the U.S.
Radon comes from the natural (radioactive) breakdown of uranium in soil, rock
and water and gets into the air you breathe. Radon can be found all over the U.S.
It can get into any type of building—homes, offices, and schools—and result in a
high indoor radon level. But you and your family are most likely to get your greatest exposure at home, where you spend most of your time.
