Photo: AFPSydney: 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 Monday. After analysing data from 20 studies of radioactivity associated with the plant, study finds radiation levels in the Pacific rapidly returning to normalFile photo. Japan shut down dozens of reactors after a magnitude 9.0 earthquake-generated tsunami on 11 March 2011 triggered one of the largest ever dumps of nuclear material into the world’s oceans. 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. The research examined radioactive caesium levels measured off Japan’s coast across the Pacific to North America.
