In plain language
In 60 orthopaedic trauma procedures, lead aprons cut surgeons' measured dose by about 91%, and estimated annual doses were well below limits. Inner thigh dose was higher during seated cases, likely because the lead skirt parted.

What it found
Lead aprons reduced measured dose by about 91% (outside versus inside thermoluminescent dosimeters (TLDs)).
Key figures: mean outside 163 µGy vs inside 14.4 µGy; 91.1% reduction
Inner thigh and knee dose was higher than whole-body dose, likely because the lead skirt parts during seated procedures.
Key figures: 2.7 mSv/yr estimated
Estimated annual torso dose under the apron was far below the category B limit.
Key figures: 0.14 mSv/yr vs 6 mSv limit
Estimated annual eye lens dose was low, based on the thyroid collar measurement.
Key figures: 0.7 mSv/yr without eye protection; <0.28 mSv/yr with lead glasses
Hip procedures and femoral nails had the highest patient dose-area product (DAP) and the highest surgeon scatter dose. Outliers were linked with high patient body mass index (BMI) but were not tested statistically.
Limits to keep in mind
This was a small single-centre study over six weeks (60 procedures, few high-dose cases) with annual doses extrapolated. Eye dose was estimated from a collar-level dosimeter, and no hand dose was measured.
