The Japanese authorities detected unusually high levels of radioactive substances in seawater near the nuclear plant accident by the earthquake, said Tuesday the operator Tokyo Electric Power (TEPCO). The level of iodine 131 and cesium 134 are respectively 1267 and 24.8 times higher than the standards set by the Japanese government, TEPCO said.
The substances were detected in seawater picked at random on Monday, about 100 meters south of the plant in Fukushima N.1, TEPCO said a spokesman. The level of cesium-137 was also 16.5 times higher while the cobalt-58 was lower than the norm, said Naoki Tsunoda, noting that these levels pose no threat to human health.
Previously, the report's French Nuclear Safety Authority (ASN) has warned that radiation leaks from Japanese nuclear plant in Fukushima rugged are "important" and a local pollution source that Japan will have to "deal for tens of years." The radioactive emissions from the Japanese central "are now very important, and continue, so Japan will have to permanently manage the consequences," said President of the ASN, André-Claude Lacoste, which predicts that will last "tens and tens of years ".
