Radiological problems of liquid waste disposal into the sea

A methodology where every external or internal irradiation aspect is explored and quantified, is presented. Study of these features includes the choice of parameters such as the dilution factor of the effluent in the sea or the consumption rate of edible sea organisms which may vary from one site to another. In a first approach, it is considered that the site is standard and doses through each exposure pathway are calculated with pessimistic assumptions for each parameter entering into the circulation. Pessimistic assumptions are chosen for French seashore sites but it is always possible to modify a parameter for a specific site when it is an evident fact. Three main population groups have been selected: the fishermen group, the nearest population group and the summer visitors. For each of these groups a definite time of exposure and a definite daily intake of edible sea products have been assumed
