All x-ray producing devices must be registered with the State of Tennessee and inspected on a recurring basis as specified in 0400-20-10-.27(3)(a) in State Regulations for the Protection Against Radiation.

Safety & Compliance Inspections

The VUMC Department of Radiology and the Department of Radiation Oncology works in partnership with VEHS Radiation Safety to manage compliance inspection for the Medical Center. Frequency of inspection is based on the classification for the device.

VEHS Radiation Safety manages compliance inspections for all x-ray producing devices registered to Vanderbilt University.  


For all non-clinical VU and VUMC x-ray producing devices, contact VEHS Radiation Safety immediately to register machines.  X-ray producing devices must be registered within ten calendar days of receipt or relocation.

For all clinical x-ray producing devices, the VUMC Policy Diagnostic Imaging X-Ray Safety states, "Any person or organizational unit bringing x-ray equipment on site must notify Radiology Administration, Clinical Engineering, and VEHS prior to installation, and within 5 days from when the equipment either arrives on site, leaves the site, or (except for mobile units) is relocated on site. Any department failing to provide this prior notification is responsible for any fees, penalties, and interest resulting from late registration of the device(s)."  Send email here to notify VUMC contacts that you have a new clinical x-ray producing devices to register.  This will notify Radiology Administration (, Clinical Engineering (, and VEHS (


All devices must be labeled with the words "Caution - Radiation - This equipment produces radiation when energized." Any entrances to rooms with fixed units must also be posted. If you need labels or postings, contact VEHS Radiation Safety.  If you work in clinical areas at VUMC, you can also contact Ryan Ross in Radiology Administration.
