In 1985 the International Atomic Energy Agency published Technical Reports Series No. 247, entitled Sediment Kds and Concentration Factors for Radionuclides in the Marine Environment, containing sediment distribution coefficients and concentration factor data for marine biological material, which could be used in models simulating the dispersion of radioactive wastes disposed of in the sea. TRS 247 has proved to be a valuable reference for radioecologists, marine modellers and other scientists working in the field of assessment of the impact of radionuclides in the marine environment. In 2000 the IAEA initiated the revision of this publication to take account of the many new data that have been gathered. The sediment distribution coefficients and concentration factors provided in the revised publication were calculated using the same approach adopted in TRS 247. These values should, therefore, be used instead of the values published in TRS 247. In addition, this revised publication contains concentration factors for a limited number of elements for marine mammals, which were not included in the first version of the report.
