| What Is Radon? |
Radon is a colorless, odorless, tasteless, and naturally occuring
radioactive gas produced by the breakdown of uranium in soil.
Radon travels freely through the ground and enters your home or
building. Once inside, radon and the decay products can cause
radiation energy damage to the human lungs. Radon, a known
human carcinogen, is measured in picocuries of radon per liter of air
(pCi/L). Radon is considered the leading cause of lung cancer in
non-smokers and the second leading cause in those who do smoke.
The U.S. Environmental Protection Agency (EPA) has established an
action level of 4.0 pCi/L and recommends that homes with radon
levels at 4.0 pCi/L or higher be mitigated.

| Radon Zones In Tennessee |
The EPA has assigned each of the counties in the U.S. to one of
three zones based on radon potential. Each zone designation
reflects the average short-term radon measurement that can be
expected in a building without radon control methods, with Zone 1
being of the highest priority.
Knox, Loudon, Blount, Roane, and Anderson Counties are assigned
Zone 1 status. Below is a map of Tennessee showing the EAP's
rating of each counties.

Knox, Loudon, Blount, Roane, and Anderson Counties are assigned
Zone 1 status. Below is a map of Tennessee showing the EAP's
rating of each counties.
Zone 1 counties have a predicted average indoor radon screening level greater than 4
pCi/L (pico curies per liter) (red zones) Highest Potential
Zone 2 counties have a predicted average indoor radon screening level between 2
and 4 pCi/L (orange zones) Moderate Potential
Zone 3 counties have a predicted average indoor radon screening level less than 2
pCi/L (yellow zones) Low Potential
