Researchers, including those from the government's Meteorological Research Institute and the Atmosphere and Ocean Research Institute at the University of Tokyo, will present the findings at a meeting of the Atomic Energy Society of Japan opening today in Higashihiroshima city in Hiroshima Prefecture.

Radioactive materials originating in the Tokyo Electric Power Co. Plant on the Pacific coast started to sink below the sea surface earlier this year and are likely to move southward in the future carried by deep-water currents, the study found.
