Radon is an invisible odorless gas. It comes from the breakdown of uranium in soil, rock, and water. Radon gas is found all over the world, and in every state in the U.S. It is present here in Madison County (a high radon risk zone). Levels can vary widely, even from home to home in the same neighborhood.
- The map shows that most of the Tennessee Valley falls into Zone 1 for levels of radon.
- The Madison County Extension Coordinator says that has to do with the limestone rock found below our feet, and our current drought and cooler temperatures aren’t helping.
- The Ag Extension Office says in the last few weeks, they’ve actually sold out of test kits, so they’ve had to place an additional order just to keep up with demand.
“In Madison County, areas like Downtown Huntsville, Gurley, and Moores Mill have 30% or more homes detected with dangerous levels of radon.”
