State Radiation Registration

State-level registration for radiation-producing machines — X-ray tubes, linacs, fluoroscopy systems, mammography units, dental X-ray, CBCT, CT, DR / fluoro rooms, mobile DR / C-arm. Distinct from NRC / Agreement-State byproduct-material licensing (which covers radioactive material). Every X-ray machine in U.S. clinical use must be registered with the state radiation-control program in the state where it operates.

What gets registered

• All medical X-ray equipment — diagnostic, fluoroscopic, interventional, mammography, CBCT, CT.
• Therapy linacs — typically registered as radiation-producing machines on the state side, paired with NRC / Agreement-State byproduct license if sealed sources or brachytherapy are co-located.
• Industrial / non-medical X-ray equipment — dental, veterinary, security, NDT — separate from the medical chain.

Typical requirements

• Registered equipment list — make, model, serial, location, install date, modality.
• Operator certification — radiologic-technologist licensure (state-specific scope, often referenced to ARRT credentials for radiologic technologists or specialty registries — RDMS / RVT / RDCS for ultrasound, CNMT / ARRT-N for nuclear medicine, etc.).
• Annual physicist survey — dose calibration, image quality, mechanical safety, shielding adequacy. For mammography, the survey is the MQSA survey on the same calendar.
• Radiation Safety Officer — required for many states and for fluoroscopy / interventional / radiation-therapy programs; scope varies.
• Shielding survey — pre-install / post-install / post-relocation. Vault repurposing requires a final survey before reuse.
• Inspection cycle — varies by state, typically every 1–4 years; some states inspect on complaint or random audit.
• Per-machine fees — annual or biennial registration fees per machine.

Why it matters to buyers

• Moving equipment between states = new registration in the destination state, not transfer of the source-state registration. Plan into install schedule.
• Shielding survey must pass state physics-survey requirements before clinical use. Existing shielding is generally retained in same-room replacements but re-surveyed.
• State-specific operator credentialing can be different across state lines; staff licensure transfers don't always carry over.
• Mobile fleet — mobile C-arms, mobile DR, and mobile mammography that cross state lines may require multi-state registration.
• Non-compliant operation — penalties range from fines to clinical-use suspension; states publish enforcement actions.

Adjacent / overlapping frameworks

• NRC / Agreement-State byproduct-material licensing — covers radioactive material (PET tracers, brachy sources, Gamma Knife Co-60), distinct from X-ray-machine registration.
• MQSA — federal mammography framework, paired with state X-ray registration.
• ACR accreditation — quality framework; reimbursement-relevant; distinct from registration.
• AAPM TG-142 — linac QA framework; per-program physicist responsibility; distinct from machine registration.

Decommissioning

State X-ray-machine registration is amended or cancelled at decommissioning. Final shielding survey documents the closure for the file. See the decommissioning hub for modality-specific paths.
