In plain language
National French dosimetry data show nuclear medicine workers averaged 0.78 mSv in 2023, with no regulatory limits exceeded for body, extremity or eye lens doses. This review covers nuclear medicine, not interventional fluoroscopy.

What it found
Average annual occupational dose for nuclear medicine workers in France in 2023 was very low, about three times below average natural background exposure.
Key figures: 0.78 mSv
No regulatory dose limit was exceeded for whole-body, extremity or eye lens exposure.
Most reported significant radiation protection events were minor and had no clinical consequence.
The authors argue the linear no-threshold model has limitations at low doses and conclude nuclear medicine is among the least exposed hospital specialties.
Limits to keep in mind
Narrative review drawing on national registry reports (IRSN 2023, ASN 2024) for France only, reported through an abstract; average doses may mask higher individual exposures, and the critique of the LNT model reflects the authors' view.
