Cruise finds Fukushima pollution
Radioactive elements from the damaged Fukushima nuclear power plant have been detected in seawater and marine organisms up to 600km from the coast.
But the scientists who made the discovery stress the natural radioactivity of seawater dwarfs anything seen in their samples.
The results come from a research cruise in June last year led by the Woods Hole Oceanographic Institution (WHOI).
Dr Steven Jayne reported the results of "drifters" put in the water to understand the movement of the ocean off Japan.
