Above 4 picocuries per liter (pCi/L) is high. If your test result is over 4 pCI/L it is recommended that you test again with either a short-term (two to seven days) or long-term (three to12 months) device. If the second test result is over 4 pCi/L you should hire a professional to fix the problem.
Short term radon tests take two-90 days (depending on the test used) and are the best first step to take when testing your home for radon. They indicate the average level of radon in your home during the testing period.
Long-term radon tests are the most accurate, but take over 90 days to complete. Long-term tests are recommended as a follow-up when a short-term test kit indicates levels are close to or slightly above 4 pCi/L. Order a long term test kit from the National Radon Program.
If the radon level in your home is over 4 pCi/L, you should consider getting your home mitigated. Mitigation is the technique used to remove the radon in your home. You should you use a registered mitigator and obtain estimates from more than one professional. In the EPA Consumer Guide to Radon Reduction, on pages 4-6, there is a helpful checklist on how to select a radon mitigation professional. For more information on mitigation, read Radon Mitigation Dos & Don'ts.
There are no laws mandating a mitigator receive certifiecation in Georgia, however, many mitigators chose to get certified by one of two national programs. The program reccomends you use a certified mitigator. Click the links below to search for a mitigator in your area.

The UGA Radon Program recommends hiring a certified radon tester to perform a test during a real estate transaction. These testers are trained to use equipment that is tamper-proof and can provide a radon result quickly within the due dilligence period. There are currently no laws mandating radon testing or certification for real estate transactions in Georgia.

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 air first and if that result is high, then test your drinking water. For more information on radon in water, visit the EPA website.
