Description
We examined the vertical distributions of 239+240Pu activity and 240Pu / 239Pu atom ratio in particles collected by large volume water in-situ pump in the western North Pacific Ocean (off Rokkasho, Japan). This is the first information of vertical distribution of plutonium activity and Plutonium atom ratio in small particle (1-70 μm) and large particle (>70 μm). (author)
