The Tennessee State Radiochemistry Laboratory supports the environmental protection functions of the state government by performing radiological analysis on samples collected by the Tennessee Department of Energy and Conservation (TDEC). Specific divisions within TDEC that collect samples for radiological analysis are the Division of Radiological Health, Division of Remediation, and the Division of Energy/Oversight.

Examples of types of samples that are analyzed include but are not limited to, routine samples taken from the vicinity of nuclear power plants, inspection samples from sites such as scrap metal facilities and privately owned wells.

The radiochemistry laboratory is certified and accredited by the American Association for Laboratory Accreditation and by the Environmental Protection Agency through a series of audits and by performance test evaluations.
