Depth profiles of concentration of $^{239+240}$ Pu and $^{240}$ Pu/ $^{239}$ Pu ratio in the cores collected from the center of the Nagasaki Bay were determined to find depositional records of plutonium released from Nagasaki atomic bomb and other nuclear tests. The ratio in sediment at the depth of about 50 cm was higher than that of the global stratospheric fallout, which might show that the plutonium has come from the nuclear tests carried out around the Marshall Islands. Deposition of plutonium from the Nagasaki atomic bomb will be also reported in the presentation.
