The Environmental Protection Agency (EPA) has designated January as National Radon Action Month. Most people are surprised to learn that radon is the second leading cause of lung cancer in the US, after smoking; exposure to both radon and smoking multiplies the risk of developing lung cancer. Radon is a naturally occurring gas that forms from the breakdown of uranium in soil, rock and water. It is also colorless, odorless, and tasteless, making it impossible to detect without special equipment. The higher a home’s radon level, the greater the health risk to occupants. Radon can be found all over the US, and average levels are particularly high in the metro Atlanta region (Figure 1).
