Plutonium isotopes were released from Nagasaki atomic bomb which exploded on August 9, 1945. The isotopes are interesting in research on environmental radioactivity, because evident information of the plutonium release provide opportunities to simplify understanding of environmental behavior of Pu. The Nagasaki area is one of the oldest areas that were contaminated with the artificial Pu in the world. As the isotopic composition of Pu depends on its origin, $^{240}$ Pu/ $^{239}$ Pu ratio is a useful tool for the identification of the source of Pu. This paper is intended to report the $^{240}$ Pu/ $^{239}$ Pu ratios in sediments and surface soils and distribution of the Pu from the atomic bomb.
