The level of radioactivity discharged into the ocean after the Fukushima disaster and its impact has been measured by researchers.
The study was conducted by Woods Hole Oceanographic Institution chemist Ken Buesseler and two colleagues based in Japan, Michio Aoyama of the Meteorological Research Institute and Masao Fukasawa of the Japan Agency for Marine-Earth Science and Technology.
While concentrations of some radionuclides continued to decrease, by July they were still 10,000 times higher than levels measured in 2010 off the coast of Japan.
This indicates that the plants “remain a significant source of contamination to the coastal waters off Japan,” the researchers report.
