[Radiation protection of operators during endoscopic retrograde cholangiopancreatography]. / Radioprotection des opérateurs lors des cholangio-pancréatographies rétrogrades endoscopiques.

Radiation hazards to operators performing retrograde endoscopic cholangio-pancreatographies (RECP) have been investigated. The principles and central elements of French medical radioprotection legislation are recalled. Doses received by the operators, over a one month period representative of their usual work, were measured in two ways: by using a ionisation chamber and with thermoluminescent detectors worn by the staff. Extrapolated to 12 months, the results were inferior to the annual reglementary dose limit: whole body < 1.2 mSv (against 50 mSv), eye lens = 38.4 mSv (against 150 mSv). Further means for reducing dose levels are proposed.
