Tokyo .- Radioactive substances 20,000 times above the legal limit annual leaked into the sea from the Japanese nuclear plant damaged Fukishima between 1 and 6 April, today reported operating company, TEPCO. According to TEPCO data collected by the local agency Kyodo, in those six days, escaped into the sea about 520 tons of highly radioactive water from the reactor 2 of the plant severely damaged by the tsunami on 11 March.
The leak was detected on April 2 and contained the 6th of that month, but by then it had leaked into the Pacific Ocean about 5,000 terabecquerels of radioactive substances, which is 20,000 times more than the maximum annual allowable plant . The amount is however far below the level of radioactivity emitted into the atmosphere from the plant, the Nuclear Security Agency of Japan estimated at between 370,000 and 630,000 terabecquerels since the beginning of the crisis.
Besides water leaked at the beginning of this month TEPCO deliberately dumped into the sea about 11,500 tons of water with relatively low radioactivity (one hundred times the limit) to make room in several reservoirs to store them much more contaminated liquid . The radioactivity has led the government to evacuate a 20-kilometer radius around the central battered, an area that from this midnight local time (15.00 GMT) will be legally declared exclusion zone.
It has also recommended to those between 20 and 30 kilometers or longer remain sheltered place, and a month before evacuation areas expand to five other localities up to 40 kilometers where high radioactivity was detected. To help prevent the spread of radioactivity in the sea, twelve days ago TEPCO installed a barrier of steel plates and a plastic mesh on the coast, which has reduced the concentration of radioactive iodine in the area, as NHK.
Yesterday, Wednesday, the government banned the distribution of a type of fish similar to sea eel in Fukushima to have detected a cesium levels of 14,400 becquerels per kilo, well above the legal limit of 500 becquerels, a sample captured in water Iwaki City in the south of the province.
