Active Radon Program: Yes
Require License for Radon Professionals: Yes

Tennessee is the 36th most expansive state in terms of size and the 17th most populous. It also happens to be the 21st most densely populated state in the entire country.

Tennessee does have an active radon program, dedicated to educating citizens about the risks associated with the deadly gas. You can find more information on Radon, testing and mitigation at the official page.

The radon levels in Tennessee are above average in many areas of the state. Some counties see 16% of homes with elevated levels, while others see 33-75% of homes. There’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Tennessee Radon Mitigation and Testing

Need your home tested for radon? Already know you have high levels and need a radon reduction system installed? Finding qualified Radon professionals can be difficult, but we've put together a list of Tennessee contractors to help you save time.

Tennessee Radon Levels

Map of Tennessee Radon Levels

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

Tennessee Radon Statistics

Tennessee has 94 counties and 38 (40%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. Tennessee's state radon zone average is 1.8, which is the average of all county zone ratings the EPA has assigned the state, ranking it 24 among all states.

Tennessee Radon Contractor License Information

Does Tennessee require contractors to be licensed? Yes.

What are the licensing requirements? The requirements are as follows:

1. Attend and complete an approved course.

2. Take and pass the national certification examination offered through the National Radon Safety Board (NRSB) or National Radon Proficiency Program (NRPP).

3. Register with the state radon program.

Those looking for a radon certification can take qualified third party courses offered by the NRPP or AASRT. The state will then endorse said professionals and add them to the official directory.

Tennessee Radon Real Estate Requirements

Does the state of Tennessee require radon testing for all real estate transactions? No

However both the state of Tennessee and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Tennessee does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. Tennessee radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
