Huffington Post, Sept. 1, 2013: [T]he [Fukushima] plume will eventually begin to escape the North Pacific gyre in an even more diluted form. About 25 percent of the radioactivity initially released will travel to the Indian Ocean and South Pacific over two to three decades after the Fukushima disaster, the model showed.
Multi-decadal projections of surface and interior pathways of the Fukushima Cesium-137 radioactive plume, October 2013: [O]ur simulations suggest that after 30 years about 25% of the initial Cs-137 release is likely to exit the North Pacific toward other oceanic basins, with most exiting via the Indonesian Throughflow and/or crossing the Equator to join the South Pacific; only a small proportion leaves via the Bering Strait into the Arctic, a pathway also simulated by Behrensetal.(2012). This finding is consistent with the analysis of interbasin transport of the previously released Cs-137 undertaken by Tsumune et al.(2011), who find that the North Pacific has been a source of Cs-137 to other ocean basins, in particular via the Indonesian Archipelago toward the Indian Ocean. This is also inline with the global simulations performed by Nakano and Povinec (2012), which indicate that the Fukushima-derived Cs-137 will be transported to the South Pacific and the Indian Ocean after 20 years.
