Radon is a hazardous, naturally occurring gas.

Radon results from the decay of trace amounts of uranium found in the earth's crust.

Radon can be present in well water, building materials, public water supplies and outdoor air.

Radon is a cancer-causing, radioactive gas.

What is Radon?

Radon is a naturally-occurring, radioactive gas found in the soil. Exposure to radon has been linked to the development of lung cancer; in fact, it is the second-leading cause of lung cancer in the US, according to the Surgeon General. It’s been referred to as “the silent killer” since it has no taste, color, or smell, and many people don’t even know what levels they are being exposed to.

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. 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. The EPA and the Surgeon General recommend testing all homes below the third floor for radon.  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. Join them today and gain the peace of mind that comes from knowing that you and your family are safe from cancer-causing radon gas
