Radioactive tritium from Fukushima found near the Southern Kuril Islands
Laboratory analyses of the first water samples obtained during the expedition of the research vessel Akademik Oparin showed elevated tritium levels in the main branch of the Kuroshio Current, which was to be expected based on the current pattern in the region, as well as elevated tritium levels in the area of the South Kuril Islands. Therefore, the goal of the new expedition is a more thorough study of the waters of the Kuril Islands and the southern part of the Sea of Okhotsk, which is the most important fishing zone in Russia, the press service of the V. I. Ilychev Pacific Oceanological Institute (TOI) of the Far Eastern Branch of the Russian Academy of Sciences told TASS.
The operator of the emergency Fukushima-1 nuclear power plant discharges low-level radioactive water, but in very large quantities
According to the company’s materials, the concentration of tritium in the water to be discharged is 55-77 becquerels per liter, which is significantly less than the established standard of 1,500 becquerels per liter. The total volume of water released from the emergency Fukushima-1 nuclear power plant in Japan during the 2023 fiscal year, which ends on March 31, 2024, will be 31.2 thousand tons with a radioactive tritium concentration of 5 trillion becquerels.
