The operator of the Japanese nuclear plant has reported that a sample taken from the center in July 2013 was five times above the originally detected values.
Electric Power (Tepco) said a new measurement has shown that the liquid taken from an observation well between 1 and 2 reactors of the plant on July 5, containing the record of 5 million becquerels per liter of strontium-90.
TEPCO originally detected 900,000 becquerels per liter of strontium and other radiation emitting substances beta before testing in October that measuring equipment suffered technical problems that prevented an accurate calculation.
Such observation well is about 25 meters from the pier of the plant and about 6 a tunnel through which highly radioactive water circulated after the outbreak of the crisis in March 2011.
Strontium-90 is a radioactive isotope with a half-life of about 30 years that tends to accumulate in bones and is believed to cause bone cancer and leukemia.
explained Electric will return analyze past samples, since many of the data are not reliable after the problem was found in measuring devices. Accident at Fukushima Daiichi plant, caused by the earthquake and tsunami of March 11, 2011, was the worst from the Chernobyl (Ukraine) in 1986. Their emissions have seriously affected agriculture, livestock and fishing locally and still have evacuated some 52,000 people living around the plant.
