How it was made
A 2025 study in the Journal of the Society for Cardiovascular Angiography and Interventions (JSCAI) found that no central repository collects state radiation rules. Read the FAQ. ORSIF's State Rules Map is a step toward one.
For each of the 50 states and the District of Columbia, an AI research assistant read the state's rules, statutes and regulator pages and answered the same 14 questions. Each answer records the rule section, a link to the source page and, where possible, a short quote. A program then checked every quote against the pages the research read for that state: 663 of 670 matched word for word. A quote that could not be matched is not shown, and its answer carries a "Check the source" flag.
On November 5, 2026, a second check went back over the weakest answers, this time reading the full source pages. An answer changed only when its new quote was found on the source page or, for a "No", when the rules it could read did not contain the requirement. Those "No" answers have no quote, and their citation says where it looked. ORSIF then fetched the linked pages again and found nearly all the printed quotes on a page linked beside them. Some official sites block automated reading, so those could not be rechecked this way.
The headline counts on this page are computed from those answers. Agreement State status comes from the NRC's own list, updated October 29, 2026. A regulatory expert has not yet reviewed these summaries. The research for Alaska, Connecticut, Montana, Pennsylvania, Virginia and Wyoming ended before every question was fully answered, and those pages say so.
What it cannot tell you
- This map is not comprehensive and not always accurate. An answer can be incomplete, out of date or wrong, and a rule can be missed or misread.
- Rules change. Each page says when it was researched and rechecked.
- "Not found" means ORSIF did not find a requirement in the rules it reviewed. It does not mean none exists.
- Only each state's rules for X-ray and fluoroscopy equipment were reviewed. Federal rules, accreditation standards and a facility's own policies can add requirements the state rules do not.
- This is education, not legal advice. Double-check any answer at the source linked on its state page, with your state's radiation control program and with your facility's radiation safety officer.
