Division of Radiological Health

The Tennessee Department of Environment and Conservation’s (TDEC) Tennessee Division of Radiological Heath (DRH) is happy to answer questions and provide technical assistance pertaining to inquiries related to ionizing radiation hazards. For program information, visit our website at: http://tn.gov/environment/section/rh-radiological-health.

There are many projects that seek TDEC- DRH’s review through a request for environmental consultation. The term “environmental consultation” includes current and future license / amendment review requests, site remediation close out survey reviews, or requests for assistance involving investigation / remediation of radiation incidents / emergencies, and Environmental Assessment or Environmental Impact Statement reviews pursuant to the National Environmental Policy Act (NEPA).1

What types of projects are suitable for environmental consultation from TDEC-DRH?

The majority of environmental consultation requests for DRH are related to license / amendment reviews, records/information requests regarding licensees, and radiation alarms in the metal recycling and landfill industries. Sometimes these can be handled over the phone or through an e-mail request. Others may require an onsite investigation.

What should I include in my request to TDEC-DRH?

When submitting a request for environmental consultation to DRH, the following information is helpful:

  • Brief description of hazard or project.
  • Property address.
  • Contact Information including Phone Number and Email address
  • Photographs, if available.
  • Radioactive isotopes and radioactivity (if known)

When should I expect to hear from TDEC-DRH?

For situations that do not involve imminent danger to lives or property, DRH staff will try to respond within two working days, or within two working days after returning to the office from an absence. Urgent requests will be handled as quickly as possible.

What should I expect to receive from TDEC-DRH?

DRH staff will initially respond to requests by telephone or e-mail. A site visit will be conducted when necessary, and may conclude with verbal or written instructions, along with a written report and/or photographs when appropriate. Environmental hazard evaluations of proposed infrastructure or other projects will usually be followed up with written comments.

Who should I contact for more information?

Requests pertaining to any of the aforementioned license / amendment review requests or environmental review requests may be submitted to Division.Radiological.Health@tn.gov. Written, electronic submittal of requests and supporting documentation are preferred.


If a draft Environmental Assessment or draft Environmental Impact Statement pursuant to NEPA has been developed, it should be sent with all supporting materials and a request for review to TDEC.NEPA@tn.gov

In addition to staffing at the Nashville Central Office, DRH staff is located at the TDEC Chattanooga, Knoxville, Memphis and
Nashville Environmental Field Offices. DRH contact information for each office can be found on the contact page linked below.
