In plain language
In one gastroenterology department, eye lens doses during endoscopic retrograde cholangiopancreatography (ERCP) averaged about 35 to 93 μSv per procedure; extrapolated annual doses for the gastroenterologist and anesthesiologist could exceed 20 mSv without eye protection.

What it found
Without eye protection, estimated annual eye lens doses to the performing gastroenterologist and the anesthesiologist can exceed the 20 mSv annual limit.
Key figures: 20 mSv per year
Mean eye dose per ERCP procedure ranged across staff positions.
Key figures: 34.9 μSv to 93.3 μSv per procedure
Fluoroscopy time per ERCP varied widely.
Key figures: 1.0 to 28.8 min; mean 4.6 min
Measurements covered four main staff positions over two months and were extrapolated to annual doses.
Key figures: 2 months; 4 positions
Limits to keep in mind
Single busy department measured over only two months, with annual doses extrapolated rather than measured; number of procedures and staff not stated in the abstract.
