Surface, intermediate and near-bottom water samples were collected at two of the North East Atlantic radioactive waste dumping sites (47∘ 14’N, 05∘ 33’W and 45∘ 27’N, 06∘ 16’W) in the course of a sampling campaign in June–July 1998. Analysis of 239,240Pu concentrations show no significant differences with respect to measured concentrations in waters taken from control (background) stations well removed from the dumping sites
