Abstract
This draft report is the result of extensive studies based on the best available information in the field of oceanography, marine radiobiology and health physics. On various basic considerations, assessment was undertaken, and the following conclusion was reached. The quantity of radioactivity to be dumped at one time is assumed to be 500 Ci in the case of test dumping, and 10/sup 5/ Ci/year in the case of full-scale dumping. The conditions required for the dumping sea area are that the bottom water flow and upwelling amount are limited, and that the sea bottom is flat. The horizontal dispersion coefficient of 10/sup 7/ cm/sup 2//sec and the vertical dispersion coefficient of 2 x 10/sup 2/ cm/sup 2//sec are assumed. It is assumed that the radionuclides in the disposed package would leached out as soon as it reaches the sea bottom, and would not show any physicochemical behavior. Typycal radionuclides are classified into 5 groups in terms of their half lives, and their estimated concentrations at 1 km depth are tabulated. The maximum level of individual dose and the magnitude of population dose were assessed on the fishermen working in the dumping sea area, and the adults, children and infants who
