[en] Directives of the European Community require that radiologic workers in the Netherlands will be subdivided in two categories A and B, on the basis of the radiation risk they are exposed to. An indication about these risks can be found in the activities of the radiologists have to carry out. Until now, there was no clear understanding of the relation between activities and radiation risks. This report provides an inventory of the radiologic work in the Netherlands, the different doses they are exposed to; a classification of these doses; dose exceeding probabilities; etc. (G.J.P.)
