Jan. 4, 2018: Now through March is a good time to test for radon, when windows and doors are closed tight to keep out the cold winter air. To help detect if there is a harmful level of radon in your home, the Knox County Health Department promotes the use of free radon test kits for individual testing by homeowners, homebuyers, landlords and tenants. In-home testing is the only way to test for radon. Click here to order a free radon test kit or click here to learn more about radon.
