According to the "A Citizen's Guide to Radon" manual on the third page:
<em>"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 </em><em>result in a high indoor radon level</em><em>. But you and your family are most likely to get your greatest exposure at</em><em> home</em><em>, where you </em><em>spend most of your time</em><em>."</em>
