The radiation accident at the Boris Kidric Institute, Vincs, Yugoslavia, on Oct. 15, 1958, resulted in heavy exposure of six scientists to a mixturue of neutrons and gamma radiation during a subcritical experiment with a zero power re actor. The reactor was constructed with natural uraninm rods suspended in a large tank which could be filled to various depths with heavy water. A team from the Oak Ridge National Laboratory, Tenn., made measurements of the radiation dose received by the exposed persons. The methods of dosimetry were essentially those used in connection with the Oak Ridge Y-12 accident and are based on tes ratio of Na/sup 24/ to Na/sup 23/ in the body or blood system. To accomplinh the measurements the zero power reactor was operated in two differert power ranges. Data are presented from computations of gamma dose leakage; studies af Na/sup 24/ activation in man-shaped phantoms; an intercomparison of French and American Na/sup 24/ calibration; measurements of the neutron flux distribution in tbe Vinca reactor room; and neutron measurements with a tissue-equivalent phantom. Individual doses were calculated as ranging from 207 to 436 rad units. Photographs and drawings are included of the equipment and experimental facilities. Results of measurements are presanted graphically. (C.H.)
