Why Homes Should Be Tested for Radon (part 1)

As the public becomes more aware of Radon, there has become an increased demand for testing of homes before a purchase. Most relocation companies now require Radon testing as part of the transaction. The EPA and State of Tennessee are increasing their awareness programs. The national average indoor radon level is about 1.3 pCi/L while outdoor radon levels average 0.4 pCi/L. The higher a home’s radon level, the greater the health risks. Did you know that Middle Tennessee is in Zone 1 of the EPA’s radon potential map (highest level)? Zone 1 is described as an area that has a predicted average indoor radon level of greater than 4 pCi/L. The level of 4 pCi/L is called the action level, where the EPA recommends that action be taken to reduce the indoor concentration of Radon.
