Radon in Alabama

History of the Radon Program in Alabama

Homes with high levels of radon have been found in every state, including Alabama. In fact, radon levels can vary greatly from home to home - even levels next door can be very different. Therefore we recommend that all homes be tested for radon.

In Alabama, 15 counties have been identified as having the highest potential for elevated radon levels. They are Calhoun, Clay, Cleburne, Colbert, Coosa, Franklin, Jackson, Jefferson, Lauderdale, Lawrence, Limestone, Madison, Morgan, Shelby and Talladega.

Radon is measured in picocuries per liter of air (pCi/L), a measurement of radioactivity. In the United States, the average indoor radon level is about 1.3 pCi/L. The average outdoor level is about 0.4 pCi/L. The U.S. Surgeon General and EPA recommend fixing homes with radon levels at or above 4 pCi/L. EPA also recommends that people think about fixing their homes for radon levels between 2 pCi/L and 4 pCi/L.
