Reported levels against EPA’s action level
pCi/L · Tennessee dashboard tooltip · 2022–2023
Read this correctly. The dashboard’s band charts are Mid-Cumberland Region totals—not Dickson County counts. No county-specific denominator or “percent above 4” can be derived from them.
02 / Building codes
No confirmed radon mandate anywhere in the county.
The code edition changes by jurisdiction. Choose a place to see what is documented—and what is not yet confirmed.
City of Dickson
Radon appendix not adoptedMunicipal Code §12-201 adopts the 2024 IRC and includes only Appendix G. Appendix BE, Radon Control Methods, is not adopted, so radon-resistant new construction is optional.
City Title 12 · Ord. #1574, Nov. 2025 ↗Unincorporated Dickson County
Adoption formalities unconfirmedA May 18, 2020 County Commission agenda recommends the 2018 IRC with Appendices L, M, N and P—excluding the 2018 radon appendix. The agenda is not proof of the final vote; resolution number and effective date remain open.
May 18, 2020 agenda ↗Town of White Bluff
Appendix status unknownA November 1, 2022 council agenda records second reading of an ordinance adopting the 2021 ICC editions. The posted code predates that action, so whether the residential radon appendix came with it is unresolved.
November 2022 council agenda ↗Town of Burns
No radon provision foundThe published municipal code adopts the 2003 IRC and lists no appendices. Its code book is dated Change 3, November 6, 2006.
Burns municipal code ↗Charlotte, Slayden & Vanleer
Current codes unverifiedCharlotte’s available online code is from the 1990s; a 1991 agreement points to the county building inspector for enforcement. No published building codes were found for Slayden or Vanleer. None of the three appears on the state residential-permit jurisdiction list.
03 / Local rules
The buyer carries the burden.
No Dickson County or municipal radon rule was found for public buildings, schools or real-estate transactions beyond Tennessee’s statewide framework.
Construction
The state residential program adopts the 2018 IRC with Appendix Q only, not the radon appendix. Locally, no jurisdiction could be confirmed as requiring a radon-resistant system.
Disclosure
Tennessee’s disclosure instructions advise buyers to use inspection contingencies. Sellers are not required to test, and qualifying new construction with a written warranty is exempt from the disclosure form.
Schools & public buildings
Annual school-building inspections include radon under state law, but Tennessee’s school radon policy is framed as encouragement. No stronger Dickson-specific rule was located.
How do I find a certified radon professional in Dickson County?
Tennessee doesn't license radon testers or mitigators, so national certification is the best way to check qualifications. The Tennessee Radon Program points residents to two directories: search them by ZIP code and widen the radius if nothing is listed nearby.
We don't recommend or rank companies. Before you hire, check the certification number in the directory yourself and ask for a follow-up test after any system is installed. Questions to ask a radon professional.
For homebuyers
Test every home. New construction included.
Dickson County’s 2022–2023 reported average is above the action level. Code does not guarantee a radon-resistant system, and disclosure does not guarantee anyone tested.

Why it matters
- Radon causes about 21,000 U.S. lung cancer deaths a year — the second-leading cause overall and the number-one cause among people who never smoked.
- Smoking plus radon raises the risk roughly ~9×.
- About 1 in 15 homes has high radon.
- Retest at least every 2 years if you have a mitigation system, and after renovations or changes to how you use the lowest floor. EPA recommends taking action at 4 pCi/L and considering it between 2 and 4 pCi/L.
