Fukushima Radiation Could Reach US Coast in 5 Years

Radioactive water from the Fukushima nuclear reactors in Japan could reach the US West Coast in the next 5–6 years, doubling the radioactivity of US coastal waters, according to simulations carried out by German oceanographers Claus Böning, Erik Behrens and colleagues from the Helmholtz Centre for Ocean Research in Kiel.

However, Böning points out that, due to considerable mixing and dilution, the level of radioactivity reaching the US will be much lower than that released by the Fukushima plant. “The levels of radiation that hit the US coast will be small relative to the levels released by Fukushima,” he said. “But we cannot estimate accurately what those levels will be because we do not know for certain what was released by Fukushima.”

Simulated distribution of contaminated water between 1 and 10 years after the Fukushima incident. The colours illustrate the dilution relative to the initial concentrations off the Japanese coast: after 1 year maximum values still exceed 0.1% (red areas); after 10 years they will have dropped below 0.01% almost everywhere (blue areas).
