Emissions of radioactive substances after the accident at the nuclear power plant "Fukushima-1" in March last year, according to estimates of the operator station of Thurso, totaled 900,000 terabecquerels that 1.5-1.8 times the figures given earlier, according to broadcaster NHK.
Total releases of iodine-131 and cesium-137 after the accident at the plant totaled 900,000 terabekkreley. This is 1.5-1.8 times the data that led the Agency for Nuclear and Industrial Safety of the Ministry of Economy and Industry of Japan and the Commission on nuclear safety in the country's government. They evaluated emissions 570,000 and 480,000 terabecquerels terabecquerels respectively.
As the broadcaster, emissions from "Fukisimy-1" does not exceed 20% of the emissions from the Chernobyl accident in 1986, which amounted to 5.2 million terabecquerels.
As previously announced, as a result of emergency on "Fukushima-1" 146 full-time employees and 21 contractor received a dose of more than 100 millisieverts of radiation — the level at which there is a slight increase in the risk of cancer. The maximum doses — over 600 millisieverts — received two statements. This high level of exposure is associated with the fact that they did not take potassium iodide tablets needed to keep the body absorb radioactive isotope — iodine-131. However, none of these statements have not experienced any deterioration in health due to exposure.
In March 2011, in the eastern part of Japan was the most powerful earthquake and subsequent tsunami, the wave height of which in some places reached 40 meters. The disaster led to a major accident at the nuclear power plant "Fukushima-1" (Fukushima Daiichi). Of 20-30-km zone of the station were evacuated 140,000 people. The accident was the third in the world on the scale of the events at the nuclear power station "Three Mile Island" in the U.S. and Chernobyl in the Soviet Union.
