RADIATION PROTECTION OF OPERATORS DURING ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY

Radiation hazards to operators performing retrograde endoscopic cholan gio-pancreatographies (RECP) have been investigated. The Principles an d central elements of French medical radioprotection legislation are r ecalled. Doses received by the operators, over a one month period repr esentative of their usual work were measured in two ways: by using a i onisation chamber and with thermoluminescent detectors worn by the sta ff. Extrapolated to 12 months, the results were inferior to the annual reglementary dose limit: whole body < 1.2 mSv (against 50 mSv), eye l ens = 38.4 mSv (against 150 mSv). Further means for reducing dose leve ls are proposed.
