Cyclotron regulation in Wyoming
Verified August 2026
One entry from the 51-jurisdiction survey, read against a small, fully enclosed, sub-MeV machine whose beam terminates inside its own vacuum chamber.
- Small machine vs. definition
- No program — No program reaches it
No applicable machine program reaches the device.

- Regulator
- Wyoming Office of Homeland Security — Radiological Services (state radiation authority; NO machine-registration program) — Wyoming has no X-ray/radiation-machine registration program (T0). WOHS Radiological Services is the state's radiation authority but covers preparedness/response only — informational link, not a registration program. (link verified 2026-09-13)
- Register / license
- No program
- Incidental-radiation exemption
- None — no machine regulations exist
- Notes (as verified 2026-08-10, medium confidence)
- Wyoming has no radiation-machine regulatory program of any kind; the state radiological services program is advisory, not regulatory. This absence-of-program label is medium-confidence: an absence cannot be proven from the sources checked.
What to do
Identify the state radiation-control program before the machine is first energized. Ask the program in writing how it classifies the machine before purchasing or building one, rather than relying on a private reading of the definition. Document the machine’s maximum energy and the fact that its beam is internal to the vacuum chamber — that record is what any classification, exemption argument, or registration review turns on.
This is information, not legal advice. Everything on this page was verified against primary sources (statutes, administrative codes, agency publications) as of August 2026. Regulatory text moves — several states recodified or rewrote their radiation rules in 2023–2026 alone — so anything consequential should be re-checked against the current text of the cited provision, and questions about a specific machine belong to the state radiation-control program or qualified counsel.
