A major international review of the state of the oceans 5 years after the Fukushima disaster shows that radiation levels are decreasing rapidly except in the harbour area close to the nuclear plant itself where ongoing releases remain a concern. At the same time, the review’s lead author expresses concern at the lack of ongoing support to continue the radiation assessment, which he says is vital to understand how the risks are changing.

New research shows that most of the radioactive fallout which landed on downtown Tokyo a few days after the Fukushima accident was concentrated and deposited in non-soluble glass microparticles, as a type of ‘glassy soot’. This meant that most of the radioactive material was not dissolved in rain and running water, and probably stayed in the environment until removed by direct washing or physical removal. The particles also concentrated the radioactive caesium (Cs), meaning that in some cases dose effects of the fallout are still unclear. These results are announced at the Goldschmidt geochemistry conference in Yokohama, Japan.
