Back to Radon Zones in the United States




Radon zones
 Zone 3 (0 counties)
 Zone 2 (39 counties)
 Zone 1 (53 counties)
  Highest Potential: counties have a predicted average indoor radon screening level greater than 4 pCi/L (pico curies per liter) (red zones)
  Moderate Potential: counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones)
  Low Potential: counties have a predicted average indoor radon screening level less than 2 pCi/L (yellow zones)
