Radon is the second leading cause of lung cancer in the United States and the Surgeon General and EPA recommend testing for radon and reducing radon in homes that have high levels. A high radon level is any reading that is over 4 picocuries per liter, pCi/L. Radon levels over 2 pCi/L still can pose a risk and in should be mitigated.
So we finally received our radon test results today and the radon level from our test was 3.5 pCi/L. As it took the US Post Office 10 days to deliver our test to the lab this result has a greater than 25% margin of error, so we will have to do another test, and probably FedEx it to the lab this time.
Given we live in a hot zone for Radon in Georgia, if the result of our second test remains in this range there is little short-term risk but given we now have three kids, two cats, and one dog, we will have to consider fixing our home to get those levels down for all of us.
