Radon Frequently Asked Questions
What is radon?
Radon is a naturally occurring
radioactive gas found in soils, rock, and water throughout the U.S. Radon causes lung cancer, and is a threat to health because
it tends to collect in homes, sometimes to very high concentrations.
How can radon affect people's health?
Almost all risk from radon comes from breathing air with radon and its decay products. Radon decay products cause
lung cancer. You can't see radon. And you can't smell it or taste it. But it may be a problem in your home. Radon
is estimated to cause many thousands of deaths each year. That's because when you breathe air containing radon, you can
get lung cancer. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United
States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your
risk of lung cancer is especially high. Radon is estimated to cause about 21,000 lung cancer deaths per year,
according to EPA's 2003 Assessment of Risks from Radon in Homes (EPA 402-R-03-003). The numbers of deaths from other
causes are taken from the Centers for Disease Control and Prevention's 1999-2001 National Center for Injury Prevention
and Control Report and 2002 National Safety Council Reports.
Is there Radon in where in the area I live
?
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. EPAMap of radon zones in Georgia.

How do I know if there is radon in my home?

recommend testing for radon in all rooms below the third floor.

What can I do to protect myself and my family from
radon?
The first step is to test your home for radon, and have it fixed if it is at or above EPA's Action
Level of 4 picocuries per liter. You may want to take action if the levels are in the range of 2-4 picocuries per liter. Generally,
levels can be brought below 2 pCi/l fairly simply.
The best method for reducing radon in your home will depend
on how radon enters your home and the design of your home. For example, sealing cracks in floors and walls may help to reduce
radon. There are also systems that remove radon from the crawl space or from beneath the concrete floor or basement slab that
are effective at keeping radon from entering your home. These systems are simple and don't require major changes to your
home. Other methods may be necessary.
People who have private wells should test their well water to ensure that
radon levels meet EPA's newly proposed standard.
