Radon can be found all over the U.S.
Radon comes from the natural decay of uranium in soil, rock, and water. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up. Radon is 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. You and your family are most likely to get your greatest exposure at home, where you spend most of your time.

You should test for radon.
Testing is the only way to know if you and your family are at risk from radon. EPA and the Surgeon General recommend testing all homes below the third floor for radon. EPA also recommends testing in schools. Testing is inexpensive and easy; it should only take a few minutes of your time. Millions of Americans have already tested their homes for radon.

You can fix a radon problem.
Radon reduction systems work and they are not too costly. Some radon reduction systems can reduce radon levels in your home by up to 99%. Even very high levels can be reduced to acceptable levels.
