Detect fish with high levels of radioactivity in various rivers and reservoirs of Fukushima

A study by the Japanese Ministry of Environment has revealed the presence of fish with high levels of radioactive cesium in rivers and reservoirs in Fukushima province that hosts the Central rugged nuclear the same name, reported Kyodo news agency on Saturday. Among the individuals with higher levels of contaminating material highlights a mountain trout with 11,400 becquerels of cesium per kilo, more than 100 times the limit of 100 per kilo bequereles established in Japan. The trout was captured in the Niida River, in the city of Minamisoma, located about twenty miles north of the Fukushima Daiichi plant, which makes it one of the most affected by the nuclear crisis and that is just edge of the perimeter of exclusion created after the accident. Detection last year of rice and beef contaminated after nuclear accident triggered by the tsunami of 2011 caused the government last April reduced from 500 to 100 becquerels per kilo limit for fruits, vegetables, grains, fish, shellfish and meat. Similarly, decreased from 200 to 50 per kilo cesium becquerles limit for milk and baby food and from 200 to 10 for water.

Other fish

The study, carried out in June and July to discuss levels of cesium in fish and insects in rivers, lakes and the coast of the province, also detected a bass with 4,400 becquerels of radioactive cesium per kilo, and a catfish with 3,000 in the Hand Reservoir in Iitate, 40 kilometers northwest of the plant. is the second analysis of this type conducted by the Ministry of Environment Japan after the first conducted between December 2011 and January this year. "As in the previous study, the concentration (radioactive cesium) has tended to be higher in the rivers and lakes in the sea. want grasp the extent of contamination by performing these tests continued, "a representative of the ministry to Kyodo. The accident at the Fukushima Daiichi caused by the devastating tsunami in 2011, the Northeast was the worst since Chernobyl in 1986, and maintains some 52,000 people evacuated within a radius of 20 kilometers.
