All About Radon

Radon is a colorless, tasteless and odorless gas that can cause lung cancer. It occurs natually when uranium breaks down to radium which in turn breaks down to form radon. Radon is released into the soil and easily enters your home through the foundation and well water. It can build up to dangerous levels inside houses, schools, and other buildings. The only way to know if you have radon is to TEST. 

Radon is the second leading cause of lung cancer in the United States, after tobacco smoke. Radon kills nearly 21,000 people each year, more than 800 of them in Georgia. Smokers are at an even higher risk of radon-induced lung cancer than nonsmokers by 7%.

The following map indicates areas at risk for higher levels of radon. Please note that this data is based on testkits distributed through our program between 2003 - 2014. There was insufficient data to determine the radon levels for counties colored grey. This map only serves as an approximation of the likelihood that your home contains higher radon levels.

Testing is the only way to know if you have dangerous levels of radon.

Testing for Radon in Air

Testing for Radon in Water

If your drinking water comes from a well or other underground source, then it could contain radon. If you have a private well, we recommend testing your drinking water. For more information on radon in water visit the EPA website.  Thanks to EPA funding, UGA now offers testing for radon in water.  For information on testing for radon in your water, contact Dr. Uttam Saha with the UGA AES Lab.

What's considered a high test result?

The Environmental Protection Agency (EPA) considers any radon test results above 4 picocuries per liter (pCi/L) to be high.

How do I fix my high results?

If the radon level in your home is above 4 pCi/L, you should get your home mitigated. Mitigation is the technique used to remove the radon in your home. You should you use a registered mitigator to ensure accurate work.
