Exposition aux radiations et mortalité chez les travailleurs du nucléaire en France

This vast cohort study covers nearly 30 000 workers at CEA and Cogema, with a mean follow-up of 17.8 years. Consistently with previous studies, it found a mortality rate lower than that of the general population. An excess risk of cancer mortality was found only for melanoma, and its association with ionizing radiation remains to be defined. As in the literature, a dose-effect relation was seen for leukemia.
