Mississippi

Radon gas can be a problem in Mississippi, but the prevalence of elevated levels of radon in homes is lower compared to other states. According to the Mississippi State Department of Health, about 7% of homes in Mississippi are estimated to have elevated levels of radon gas. The Mississippi State Department of Health recommends that homeowners test their homes for radon gas, especially if they are buying or selling a home. The department provides information and resources on radon testing and mitigation on its website. Mississippi law requires that radon testing be conducted in public schools at least once every five years. The Mississippi State Department of Health provides information on its website about radon testing in schools and offers a radon testing kit loan program to schools. While the prevalence of elevated levels of radon in homes is lower in Mississippi compared to other states, it is still important for homeowners to test for radon gas and take steps to mitigate elevated levels to reduce the risk of lung cancer and other health problems associated with radon gas. 

United States EPA State Map of Radon Gas Concentration

The U.S. EPA and the U.S. Geological Survey have evaluated the radon potential in the U.S. and have developed this map is to assist National, State, and local organizations to target their resources and to assist building code officials in deciding whether radon-resistant features are applicable in new construction. This map is not intended to be used 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 geographic location. The map assigns each of the 3,141 counties in the U.S. to one of three zones based on radon potential. Each zone designation reflects the average short-term radon measurement that can be expected to be measured in a building without the implementation of radon control methods. The radon zone designation of the highest priority is Zone 1.

	Zone 1	Highest Potential (greater than 4 pCi/L)
	Zone 2	Moderate Potential (from 2 to 4 pCi/L)
	Zone 3	Low Potential (less than 2 pCi/L)
