Measurement of radiation to the hands during orthopedic surgery

: The irradiation dosis to which the surgeon's hands are submitted during operations carried out under control of the orthogonal fluoroscopic examination with image intensifier has been measured by lithium-fluoride ring-dosimeters. This measured dosis is low: 62,3 mrem on the average by operation and by person, e.a. a dosis 19 time less than the maximum weekly admissible dosis, which is 1.200 mrem. The risk run is thus very acceptable as far as the operations are not too numerous weekly for the same team, and also that utilizers are conscious of the necessity of respecting most elementary rules of prudence as much for themselves as well for their collaborators.
