Yes, you should get a Radon test for your new home no matter where you live. EPA estimates 1 in 15 homes have levels at or above the recommended levels of Radon. Radon is prevalent in Tennessee. If you have never had your current home tested, it is recommended to have it tested to see what your exposure and risk levels may be.
Why is Radon so bad? Radon is a radioactive gas that you cannot see, smell, or taste. Radon is a decay product stemming from Uranium in soil and rock. It finds its way into your home through cracks and other holes in your foundation (crawlspace or slab). As it breaks down and you breathe in the decayed products it can attach to your lungs causing lung cancer. The only way to know if you have Radon in your home is through testing.
