[Operator exposure levels in nuclear medicine studies].
In diagnostic examinations performed in nuclear medicine, radio-isotopes with a relatively short half-life are used, the quantity varying according to the type of examination. After administration of the labelled substance, the patient becomes a large source of ionizing radiations. During the course of a scintigraphic examination, the operator is obliged to go near the couch to assist the patient in the positions and will therefore inevitably be in this radiation field. The paper reports the radio-activity levels recorded at gonad and eye levels of the operator in positions most frequently held during the course of the most commonly performed scintigraphic examinations using a G.E. STARCAM 500 A gamma-camera.
