- The U. S. Environmental Protection Agency estimates that indoor radon exposure may result in 21,000 lung cancer deaths annually in the United States.
- Radon may be second only to smoking as a cause of lung cancer. Increased use of medical radiation also contributes to the annual radiation dose.
- The combination of smoking and radon exposure results in a higher health risk.
- Current technology can easily decrease the concentration of radon in indoor air, and radon’s associated risk for producing lung cancer.
