Summary

Between 1998 and 1999, 160 incidents with possible consequences in terms of external or internal exposure of workers or members of the public and with recorded estimation and/or measure of exposure were reported to the former French public radiation protection institute “Office de Protection contre les Rayonnements Ionisants”. This study describes the characteristics of these incidents in terms of place and circumstances of discovery and possible or confirmed consequences. There was a broad diversity in the place of discovery, 57% in nuclear industry, 19% in research laboratories and 14% in medical facilities. As a whole, 369 persons were concerned by these 160 incidents, 305 were susceptible to be contaminated, 54 to be irradiated and 10 presented the two susceptibilities. Measures confirmed the internal contamination for 112 persons. Among the 64 persons susceptible to be irradiated, 34 received a dose, and 4 a dose higher than 50 mSv. Due to the high frequency of contamination incidents, it would be necessary to emphasize studies focused on radionuclides used in research laboratories and medical facilities in order to improve expertise in these sectors.
