Radiation still leaking into nearby Japanese waters 18 months after quake, tsunami

FukushimaMore than 18 months after a magnitude 9.0 earthquake, 40-foot tsunami and nuclear power plant woes that struck Japan starting March 11, 2011, levels of radioactive cesium 134 and cesium 137 originating from the crippled Fukushima-Daiichi plant remain elevated in some fish and seafood in nearby waters.

That suggests that radiation from the plant is still being released into the ocean, wrote Ken Buesseler, a marine of the Woods Hole Oceanographic Institution in Woods Hole, Mass., in a perspective article in Friday's edition of the journal Nature.

Buesseler reviewed data on radionuclides in fish and other seafood that have been compiled by the Japanese Ministry of Agriculture, Forestry and Fisheries since March 23, 2011. Cesium levels were highest in bottom-dwelling fish caught near Fukushima prefecture, and lower in fish who live in the open ocean or closer to the surface, Buesseler reported.

He also noted that cesium levels had not declined, except "perhaps" in surface-dwelling fish. Over time, cesium that accumulates in the muscle tissue of fish should decline at a loss rate of a few percent per day. From this Buesseler reasoned that "there must be a continued source of cesium contamination associated with the seafloor." One possibility could be radionuclides from Fukushima lurking in ocean bottom sediments.
