Uranium is naturally present in the diet, at highly variable levels, leading to detectable activity in excreta, independently of occupational exposure to uranium. The interpretation of bioassay data from individual routine monitoring of workers occupationally exposed to uranium dioxide must therefore take this dietary intake into account to estimate doses. In order to do this, the authors tested different approaches on a group with occupational exposure and propose an original method to compare the bioassay results of an exposed group of workers with those obtained from a control population. This method allows the determination of an annual collective committed effective dose from exposure to uranium dioxide.
