By March of 2014 a strongly diluted plume of ocean water containing
radionuclides from the 2011 Fukushima nuclear incident in Japan will
reach the west coast of North America
However, the plume, which contains cesium-137, is so diluted it will be
harmless, according to the report, which cites the power of two
energetic currents off the Japan coast
Study co-author Erik van Sebille, an oceanographer at the University
of New South Wales in Sydney, said that a measurable increase in
radioactive material will be observable on the west coast of the United
States by the three-year anniversary of the Fukushima nuclear incident.
"However, people on those coastlines should not be concerned as the
concentration of radioactive material quickly drops below World Health
Organization safety levels as soon as it leaves Japanese waters," he
said in a news release.
Oceanographer van Sebille said over time "the great majority of the
radioactive material will stay in the North Pacific, with very little
crossing south of the Equator in the first decade. Eventually over a
number of decades, a measurable but otherwise harmless signature of the
radiation will spread into other ocean basins, particularly the Indian
and South Pacific oceans."
