Results of the EKO-1 project for the period 1994 - 1997 are summarised in this
report. The aim of the project was to make a joint Nordic study on radionuclides in
sediment and water and the interaction between these two phases. Relatively less
emphasis has been put on this factor compared to others in previous Nordic studies
on marine radioecology. For some of the participating countries this work was the
first of its kind undertaken. The project work involved field, laboratory and model
studies. Results of the study have appeared in various scientific journal and it has
formed the bases for two Ph.D. theses and two M.Sc. theses.
