Tennessee Department of Health provides an interactive radon map of radon test results. The short-term indoor air radon test results data are shown as radon test results aggregated by county and zip code. All testing was done voluntarily, not at random. Radon data came from a contract between the Tennessee Department of Environment and Conservation (TDEC) and Air Check, a private testing laboratory. Many of the test results were performed using free radon test kits offered by TDEC through their cooperative agreement with the U.S. Environmental Protection Agency. Some of data represent tests performed privately by individuals or radon professionals.
The Tennessee map includes the following layers:
• Tennessee geology map
• Percent of results greater than 4 pCi/L
• Average test results by zip code area
• Average radon test results by county
