About Radon

Radon is a cancer-causing radioactive gas that comes from the natural decay of uranium found in nearby soils, rock and water. Radon gets into the air you breathe. It is an odorless, colorless and tasteless gas that can cause problems in your home. Radon is estimated to cause many thousands of deaths each year. According to the National Academy of Science's Biological Effects of Ionizing Radiation or (BEIR) VI Report: "The Health Effects of Exposure to Indoor Radon," USEPA and the Surgeon General, radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. In 2003, EPA revised its risk assessment for radon in homes and estimated 23,000 lung cancer deaths per year due to radon exposure in homes.

Problems may arise when radon concentrations reach high levels in areas where people spend large amounts of time. Testing is the only way to know if you or your family may be at risk from high radon levels. EPA and the Office of the Surgeon General recommend that all homes below the third floor be tested for radon. EPA recommends mitigating homes with radon.

All homes should test for radon, regardless of geographic location or zone designation

The Map was developed using five factors to determine radon potential: indoor radon measurements; geology; aerial radioactivity; soil permeability; and, foundation type. Radon potential assessment is based on geologic provinces. Radon Index Matrix is the quantitative assessment of radon potential. Confidence Index Matrix shows the quantity and quality of the data used to assess radon potential. Geologic Provinces were adapted to county boundaries for the Map of Radon Zones.

Sections 307 and 309 of the Indoor Radon Abatement Act of 1988 (IRAA) directed EPA to list and identify areas of the U.S. with the potential for elevated indoor radon levels. EPA's Map of Radon Zones assigns each of the 3,141 counties in the U.S. to one of three zones based on radon potential:

zone 1 Zone 1 counties have a predicted average indoor radon screening level greater than 4 pCi/L (pico curies per liter) (red zones) Highest Potential
zone 2 Zone 2 counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones) Moderate Potential
zone 3 Zone 3 counties have a predicted average indoor radon screening level less than 2 pCi/L (yellow zones) Low Potential
