I found these charts below about radon levels in Cobb and Fulton Counties and found them interesting. There are also websites that show the areas with the highest levels. Of course, mitigation systems remain a way to address this and I still have all my clients test for radon and remediate prior to purchase of a home.
I continue to get higher radon readings all throughout Atlanta in the fall than I do other times of the year.
Radon is a radioactive element that is part of the radioactive decay chain of naturally occurring uranium in soil. You can’t see, smell, or taste radon gas, but it can kill you. Unlike carbon monoxide and many other home pollutants, radon’s adverse health effect, lung cancer, is usually not produced immediately. Thus you may be exposed to radon for many years without ever suspecting its presence in your home.
Radon has been found in homes throughout the United States. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. How does radon enter your home? Houses act like giant chimneys. As the air in the house warms, it rises to leak out the attic openings and around the upper floor windows, creating a small suction at the lowest level of the house, pulling the radon out of the soil and into the house.
Fortunately, there are other extremely effective means of keeping radon out of your home. Some houses have tested as high as 2,000-3,000 pCi/, yet there hasn’t been a single house that could not mitigate to an acceptable level. Mitigation usually costs between $800-$2500.
Radon is the second leading cause of lung cancer in the US, after tobacco smoking. It is the leading cause of lung cancer in non-smokers, and kills more than 22,000 people each year, 600 of them in Georgia. Protect your family from this dangerous carcinogen. Test your home today. You can prevent and reduce entry of radon into your home!
