1. Radon is a naturally occurring, colorless, odorless, tasteless radioactive gas.
2. According to the Surgeon General of the United States, radon is the second leading cause of lung cancer in the U.S. The National Academy of Sciences estimates that radon causes 15,000-22,000 lung cancer deaths each year in the U.S.
3. The adverse health effects of radon have been verified by the most extensive studies ever of human subjects for any environmental hazard. Over 69,000 miners from all over the world, working in all types of mines were studied from the first day they entered a mine until the day they died. The conclusion of these studies is that where elevated levels of radon exist, there is an increased incidence of lung cancer.
4. Homes with elevated levels of radon have been found in every state in the union. According to estimates made by the U.S. Environmental Agency (EPA), 1 in 15 homes have an elevated radon level.
5. There is no "safe" level of radiation exposure. However, the EPA has set an action level of 4pCi/L (picoliters of radon per liter of air).
6. The EPA and Surgeon General recommend radon tests for all homes below the third floor.
7. Cobb, Dekalb, Fulton, and Gwinnett Counties are listed by the EPA as
"Zone 1", that is, the highest likelihood of elevated radon.
8. The only way to know the radon level in a given home is to TEST it. The existence or non-existence of radon in a neighboring house is not a predictor of the level in any other house.
9. Radon testing is safe, easy and inexpensive.
10. Radon levels can be reduced. Radon mitigation is relatively inexpensive and is accomplished using common construction materials and methods. The EPA estimates the cost to lower radon levels in the average home to be $800-$2,500.
