About Radon Gas
Radon is a colorless, odorless, and tasteless radioactive gas that can cause lung cancer. Radon occurs naturally when uranium breaks down radium which in turn breaks down to form radon. Radon gas is released into the soil and easily enters buildings through the foundation, around plumbing, and well water. It can build up to dangerous levels in homes, schools and other buildings. The only way to determine if you you have high levels of radon gas is to test for it. Radon is measured in picoCuries per liter of air, or pCi/L. A curie is a unit of radioactivity equivalent to 1 gram of radium and the prefix "pico" means one trillionth.
The average inside air is about 1.3pCi/L there is no such thing as a zero level. The average outside air is 0.4 pCi/L. A test reading of 4.0 pCi/L is considered the action level.
Why is radon dangerous ?
Radon is the second leading cause of lung cancer in the United States, after tobacco second hand smoke. Radon kills nearly 21,00 people each year, more than 800 of them in Georgia. Smokers are at a higher risk or radon-induced lung cancer than nonsmokers
Georgia Counties risk levels.
The map below indicates areas at risk for higher levels of radon. The data is based on test results between March 2003 and July 2017.The white colored counties had insufficient data to determine the radon levels. This map only serves as an approximation of the likelihood that your home contains higher radon levels.
