[Image intensifiers in Osteosynthesis a danger for the team? (author's transl)].

Three years' examination of X-ray load when working with the X-ray image intensifier have led to the conclusion that with a tolerance basis of 100 mrem per week a fluoroscoping time of about 1 hour is tolerable without lead protection with an average fluoroscoping time of 5 minutes for one osteosynthesis. The operating surgeon can carry out about 10 osteosyntheses per week. For the other members of the operating team the X-ray load is significantly lower and, therefore, there are no limits in practice. It must be noted that an exact record of the fluoroscoping time and dose measurements is absolutely necessary.
