| 内容記述 | The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident has caused large amounts of anthropogenic radionuclides to be released into the atmosphere as well as directly discharged into the sea. To obtain the vertical distribution of Pu isotopes in marine sediments and to better assess the possible contamination from the FDNPP accident in the marine environment, activities of 239+240Pu and 241Pu, as well as the atom ratios of 240Pu/239Pu and 241Pu/239Pu, were investigated in a sediment core collected from the western North Pacific in July 2011. The observed vertical profile of 239+240Pu activities and 240Pu/239Pu atom ratios showed no extra injection of Pu from the accident, indicating no immediate Pu contamination from the FDNPP accident in the marine sediments in the region investigated. | |||||
