Abstract
The values of Derived Limits of Effluent Water Concentration, (DLEC)w, have been estimated in accordance with the principles of the recent recommendations of the International Commission on Radiological Protection.
The (DLEC)w's were derived from the Annual Limits on Intake for individual members of the public (ALIp), considering realistic models of exposure pathways and annual intake rates of foods. The ALIp's were decided after consideration of body organ mass and other age dependent parameters. We assumed that the materials which brought exposure to the public were drinking water, fish, seaweed, invertebrate and seashore. The age dependence of annual intake rate of food might be proportional to a person's energy expenditure rate. The following results were obtained. Infants were the critical group of the public at the time of derivation of (DLEC)w. The ALIp's for the infants were about one-hundredth of those for workers and their (DLEC)w's were about one-third of those for the adult members of the public.
