MISSISSIPPI - EPA Map of Radon Zones http://www.epa.gov/radon/zonemap.html The purpose of this map is to assist National, State and local organizations to target their resources and to implement radon-resistant building codes. This map is not intended to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested, regardless of zone designation. WASHINGTON IMPORTANT: Consult the publication entitled "Preliminary Geologic Radon Potential Assessment of Mississippi" (USGS Open-file Report 93-292-D) before using this map. http://energy.cr.usgs.gov/radon/grpinfo.html This document contains information on radon potential variations within counties. EPA also recommends that this map be supplemented with any available local data in order to further understand and predict the radon potential of a specific area.
