High radioactivity levels were discovered in fish in rivers and reservoirs in Fukushima, the region where last year’s tsunami triggered an explosion at a nuclear plant.
Among the highest levels of contamination were found in a mountain trout, with 11,400 becquerels of cesium per kilogram, which is more than 100 times the maximum limit accepted in Japan. The trout was caught in the Niida river, in the city of Minamisoma, about 20 kilometers north of the Fukushima nuclear plant.
The study was made last June and July and cesium levels were studied in fish and insects in rivers, coastal waters and lakes in the Fukushima Prefecture.
Radiation-related problems were recorded in Japan after last year’s accident, in products like fruit, vegetables, cereals, seafood, fish and meat.
More than 50,000 people were evacuated from the Fukushima area after last year’s accident. The recovery of the region could take decades, experts said.
