Please double-check this information. This is an ORSIF research summary, researched November 3, 2026. It is not comprehensive and not always accurate: rules change, and answers may be incomplete, out of date or wrong. It is education, not legal advice. Not yet reviewed by a regulatory expert. Confirm each requirement at the source linked beside the answer, with the state program and with your facility's radiation safety officer. How this was made

In brief

ORSIF's research identified the Bureau of Radiological Health, Iowa Department of Health and Human Services (Iowa HHS) as the agency that regulates X-ray and fluoroscopy equipment in Iowa. Iowa is a U.S. Nuclear Regulatory Commission (NRC) Agreement State: it has signed an agreement with the NRC to regulate certain radioactive materials itself.

Iowa replaced its radiation rules under Executive Order 10, effective 7/1/26, with Chapter 37 effective 7/29/26. The binding ALARA duty for X-ray registrants is in shared Chapter 37.11, which is consistent with 10 CFR Part 20. Dose limits follow the federal model, including a 150 mSv lens limit. All fluoroscopy workers must be badged. Aprons of at least 0.25 mm lead equivalent are required in interventional rooms and must be inspected annually. Apron alternatives are not addressed. Technologists need an American Registry of Radiologic Technologists (ARRT)-based permit and direct supervision for fluoroscopy; ARNPs may supervise after a course.

Which rules cover X-ray and fluoroscopy equipment in Iowa?

YesCheck the source

641-Chapter 40 (ARC 0180D, effective 7/1/26) covers X-ray and fluoroscopy, with fluoroscopy in rule 40.6. General protection standards are in 641-37.11 (ARC 0387D, effective 7/29/26). Related chapters are 38 (operator permits), 39 (radioactive materials) and 42 (therapy and analytical machines). Pre-July 2026 numbering (Chapters 40/41) is out of date.

Does Iowa require X-ray users to keep doses as low as reasonably achievable (ALARA)?

Yes

Yes, binding on registrants under 37.11(2)"b". 37.1(7) uses weaker 'should be made' wording, and ALARA is defined in 37.2.

Where ALARA lives in Iowa: In a shared rule and in X-ray-specific language. The binding occupational ALARA duty is in shared Chapter 37 (37.11(2)"b"), which applies to registrants and licensees and is consistent with 10 CFR Parts 19/20. Materials licensees also follow Part 20 by reference as amended to August 1, 2025. Chapter 40 mentions ALARA only for patient shielding (40.4(9)"b") and for staff not wearing aprons (40.6(14)"d").

Dosimeters

When a worker must wear a dosimeter, and where.

When must a worker in Iowa wear a dosimeter?

YesCheck the source

Adults likely to exceed 10% of a limit in a year must be monitored. All individuals working with medical fluoroscopic equipment must be monitored regardless of expected dose. Declared pregnant workers likely to exceed 0.1 rem (1 mSv) must be monitored. Dosimeters must be processed by a National Voluntary Laboratory Accreditation Program (NVLAP)-accredited processor.

Where must the dosimeter be worn in Iowa when a protective apron is worn?

In partLess certain

Eye-dose badge goes at the collar outside the apron, or at an unshielded spot closer to the eye. Fetal badge goes at the waist under the apron. Extremity badge goes on the highest-dose extremity. Badges under protective clothing follow National Council on Radiation Protection and Measurements (NCRP) Report No. 57, Chapter 4. Deep dose must be used for effective dose equivalent (EDE) unless a department-approved method is used, but no named approved method was found.

Aprons and alternatives

Protective apparel, how it is checked, and whether other systems are addressed.

Must staff in Iowa fluoroscopy rooms wear protective aprons or other apparel?

Yes

Aprons of at least 0.25 mm lead equivalent must be worn by all except the patient in interventional/special-procedure rooms (brief occupants may skip them if badge reports confirm low exposure) and in sterile-field cases. Barriers with viewing panels of at least 0.5 mm must be available. Ancillary shielding must be used on stationary systems, and sufficient apparel must be kept on hand. No rule requires wearing thyroid shields or eyewear.

Who may use fluoroscopy equipment and what training the rules ask for.

Who may operate fluoroscopy equipment in Iowa?

UnclearLess certain

An Iowa permit is required, except for physicians, PAs, chiropractors, dentists, hygienists, podiatrists, certified dental radiographers and students. Limited permit holders may not perform fluoroscopy. Technologists and students need direct supervision by a licensed practitioner, radiologist assistant or ARNP. ARNPs may supervise after a course, but it is unclear whether they may operate. A licensed practitioner must interpret all images.

What training or credentials does Iowa require to operate fluoroscopy equipment?

Yes

Technologist permit requires passing the ARRT radiography exam and 24 continuing education (CE) hours every two years. Radiologist assistants need formal education, one year as a technologist, the ARRT RA exam and 50 CE hours. All fluoroscopy operators need qualified-expert training in eight topics and competence in dose-saving features. Supervising ARNPs need a course. There is no separate fluoroscopy permit, set hour count or physician-specific requirement.

Changes on the way, and recent ones

Rules, bills and guidance the research found from 2025 and 2026, with the ones that touch fluoroscopy teams first.

  • Adopted ruleChapter 37 General Provisions for Radiation and Radiation Protection Standards (ARC 0387D)

    Adopted; effective July 29, 2026

    Proposed as ARC 9772C (11/26/25), amended as ARC 0223D (4/29/26), adopted in IAB 6/24/26 with no comments and no changes.

  • Adopted ruleChapters 38-42 rewrite under Executive Order 10 (ARC 0288D, 0179D, 0180D, 0181D, 0182D)

    Adopted; effective July 1, 2026

    Full Red Tape Review replacement of Chapters 38-42; the new chapters carry a rescission date of 7/1/31.

Also worth knowing

  • Every fluoroscopy worker must wear a dosimeter, not only those above 10% of a limit.
  • A dose-area-product monitor is required on interventional and special-procedure units (40.6(16)).
  • Facilities need a written patient-dose policy following ACR-AAPM guidance or NCRP Report 168, and field size must be kept minimal under sterile-field conditions.
  • A qualified expert must test fluoroscopy equipment at least every 12 months (40.6(6)).
  • Outdated cross-references: 37.11(2)"d" points to 40.4(9)"b", now a patient-shielding provision; 481-621.4(5) points to 641-38.2, now the exemptions rule.
  • There was a gap of about four weeks between the Chapter 40 effective date (7/1/26) and the Chapter 37 effective date (7/29/26).
  • Iowa has not adopted a lower lens limit; it remains 150 mSv per year.

What ORSIF could not confirm

Questions the research could not settle. If you know the answer, tell us.

  • Pending changes after June 2026 (bulletins July-November 2026 and 2026 bills) could not be checked.
  • Whether Iowa HHS commented on the NRC ALARA proposal or plans to change 37.11 or update the Chapter 39 reference date.
  • Which dosimetry method is department-approved under 37.11(3)"c".
  • Whether ARNPs or other unlisted clinicians may operate fluoroscopy, and how to read "and" in 40.6(13)"c".
  • Why the general technologist definition omits fluoroscopy although 40.6(15) assumes technologists perform it.
  • How the bureau treated occupational standards for X-ray registrants during the July 1-28, 2026 gap.

Double-check before you rely on this page

ORSIF compiled this page from the sources linked on it and did its best. It is not comprehensive and it is not always accurate. Rules change, a rule may have been missed or misread, and the sources themselves can be out of date. Treat this page as a starting point.

Where to check

What may be missing here

  • 2 of 14 answers on this page are "Not found" or "Unclear". That means ORSIF did not find the answer in the rules it reviewed, not that no rule exists.
  • 4 answers carry a flag or a lower confidence ("Check the source" or "Less certain").
  • Researched November 3, 2026. Rules may have changed since.
  • Only the state's rules for X-ray and fluoroscopy equipment were reviewed.
