What Wisconsin's rules say about ALARA (as low as reasonably achievable), dose limits in millisieverts (mSv), dosimeters, aprons and training for the people who work in fluoroscopy labs.
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 It is not comprehensive and not always accurate: rules change, and answers may be incomplete, out of date or wrong.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
ORSIF's research identified the Wisconsin Department of Health Services (DHS), Division of Public Health, Radiation Protection Section as the agency that regulates X-ray and fluoroscopy equipment in Wisconsin. Wisconsin is a U.S. Nuclear Regulatory Commission (NRC) Agreement State: it has signed an agreement with the NRC to regulate certain radioactive materials itself.
Wisconsin's ALARA requirement is in shared DHS 157.21, which covers X-ray registrants, and the X-ray chapter adds its own minimize-exposure language. Dose limits are 50 mSv whole body and 150 mSv lens; the lower 20 mSv lens limit has not been adopted. All fluoroscopy operators must wear a dosimeter, and the rule sets apron badge placement and dose formulas. Facilities must supply protective garments and X-ray them for defects every 2 years. Engineered alternatives to aprons are not addressed. Licensed practitioners or trained technologists under supervision may operate fluoroscopy. Pending CR 26-033 would rewrite the operator and supervision language.

Which rules apply, and whether ALARA is among them.
Yes. Wisconsin is an Agreement State; its agreement took effect August 11, 2003.

All radiation rules are in Wis. Admin. Code ch. DHS 157. General standards are in Subchapter III (DHS 157.20-157.33), X-ray rules are in Subchapter VIII (DHS 157.74-157.86), and fluoroscopy is in DHS 157.76. The official text was read only through excerpts and secondary copies. The DHS version note appears internally inconsistent.
Rules are specified in Wis. Admin. Code ch. DHS 157This quote was matched word for word to the source page.
Yes. DHS 157.21(2) applies to licensees and registrants, including X-ray facilities, and requires procedures and engineering controls that keep occupational doses ALARA. The radiation protection program must be reviewed at least every 13 months.
Where ALARA lives in Wisconsin: In a shared rule and in X-ray-specific language. The ALARA requirement is in shared Subchapter III (DHS 157.21), which applies to licensees and registrants. The X-ray chapter separately requires procedures to minimize personnel exposure (DHS 157.74(2)(h)) without using the term ALARA. DHS 157.74(2)(i) cross-references the dose limits but not 157.21. Because 157.21 is shared, NRC-driven changes could reach X-ray registrants. (DHS 157.21(2); DHS 157.74(2)(h)-(i))

The annual limits for workers, written in millisieverts (mSv). Ten mSv equal one rem.
0.05 Sv (5 rem) = 50 mSv per year total effective dose equivalent for adults.
0.15 Sv (15 rem) = 150 mSv per year. Wisconsin has not adopted a lower lens limit, and the pending CR 26-033 draft does not appear to change it.
A lens dose equivalent of 0.15 Sv (15 rem).This quote was matched word for word to the source page.
0.5 Sv (50 rem) = 500 mSv per year to the skin of the whole body or any extremity.
5 mSv (500 mrem) to the embryo/fetus of a declared pregnant woman over the whole pregnancy, with efforts to avoid large month-to-month variation.
When a worker must wear a dosimeter, and where.
A dosimeter is required for adults likely to exceed 10% of a limit, for minors and declared pregnant women above lower thresholds (1 mSv for a declared pregnant woman), for anyone entering a high radiation area, and for every individual operating medical fluoroscopic equipment regardless of projected dose. Dosimeters must be individually assigned and not shared. CR 26-033 would delete the badge-exchange language.
5. An individual operating medical fluoroscopic equipment.This quote was matched word for word to the source page.
When an apron is worn, the badge goes at the neck (collar) outside the apron, with an optional second badge under the apron at the waist. Two-badge formula: HE = 1.5 HW + 0.04 HN. With one badge, the deep dose counts as the effective dose if exposure is under 25% of a limit; above 25%, it is the deep dose × 0.3. DHS may approve other methods. A ring badge is required for an unprotected hand in the beam unless clinically contraindicated.
If a protective apron is worn, the individual monitoring device shall be located at the neck, which is the collar.This quote was matched word for word to the source page.
Protective apparel, how it is checked, and whether other systems are addressed.
At least 0.5 mm lead equivalent is required for body parts in the useful beam. Others must be behind whole body protective barriers of at least 0.25 mm lead equivalent or stay at least 2 m away. Operators of C-arms at 0.2 mA or less are exempt from wearing an apron if they wear a dosimeter, which implies an apron requirement otherwise. Facilities must supply enough garments for personnel otherwise not shielded. There is no explicit thyroid-shield requirement for fluoroscopy, and no eyewear requirement was found.
0.2 mA are exempt from the requirement to wear a leaded apron, provided the operator wears a personal dosimeterThis quote was matched word for word to the source page.
Garments must be inspected fluoroscopically or radiographically at least every 2 years and replaced if defective. A visual inspection showing possible defects triggers a radiographic or fluoroscopic inspection.

Not addressed. The rules require whole body protective barriers or distance, and the garment-supply rule covers personnel 'otherwise not shielded'. Whether an engineered system counts as a barrier is not stated. CR 26-033 would change 'leaded shielding garments' to 'radiation protective garments and devices'.

Who may use fluoroscopy equipment and what training the rules ask for.
A licensed practitioner or a radiologic technologist trained in fluoroscopy may operate. Technologists work under a licensed practitioner's supervision, and students need direct supervision. Diagnostic X-ray operators need a radiography license or LXMO permit, with statutory exemptions for physicians, PAs, chiropractors, dentists and dental staff, podiatrists, and supervised students. The LXMO scope does not include fluoroscopy. Nurse practitioners are not exempt; SB 281/AB 295 failed. 'Licensed practitioner' was not defined in the retrieved text.
only a licensed practitioner or a radiologic technologist who is trained in the safe use of fluoroscopic x-ray systems is allowed to operate these systems.This quote was matched word for word to the source page.
Fluoroscopy operators must be ABR-certified or board eligible, or have completed training covering specified topics. No hours are specified and there is no state fluoroscopy permit. Radiographers need the American Registry of Radiologic Technologists (ARRT) exam or certification and 24 continuing education (CE) hours every two years; LXMO holders need 12 CE hours every two years. No annual training requirement was found.

Rules, bills and guidance the research found from 2025 and 2026, with the ones that touch fluoroscopy teams first.
Sent to Rules Clearinghouse 6/22/26; public hearing 9/25/26; comments closed 10/2/26; scope expires 12/24/26; no later status found (Sep 25, 2026)
Would require fluoroscopy operators to be authorized under ch. 462 and specifically trained; technologists would work under direct supervision and students under personal supervision; 'leaded shielding' would become 'radiation protective garments and devices'; the badge-exchange language would be deleted. No ALARA or lens-limit changes found.
Failed to pass (Mar 23, 2026)
Would have added advanced practice nurses to the radiographer licensing exemptions.
Effective 7/1/2023 (Jul 1, 2023)
Set program review at 13 months, amended parts of DHS 157.74 and 157.76, and repealed patient gonad shielding (DHS 157.74(2)(e)).
