Radiation levels across the Pacific Ocean are rapidly returning to... Radiation levels across the Pacific Ocean are rapidly returning to normal five years after a meltdown at the Fukushima nuclear plant spewed gases and liquids into the sea, a study showed on Monday. Japan shut down dozens of reactors after a magnitude 9.0 earthquake-generated tsunami on March 11, 2011 triggered one of the largest ever dumps of nuclear material into the world’s oceans. The research examined radioactive caesium levels measured off Japan’s coast across the Pacific to North America. Caesium is a by-product of nuclear power and is highly soluble in water, making it ideal for measuring the release of radioactive material into the ocean, it said.
