15 lis 2024 · The Map of Radon Zones was developed in 1993 to identify areas of the U.S. with the greatest potential for elevated indoor radon levels based on indoor radon measurement data, geology, aerial radioactivity, soil parameters, and foundation types.
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)
