Tokyo, July 9 : Groundwater radiation levels reported alarm 90-folds increase in last just 3 days at Japan’s Fukushima Daiichi nuclear power plant site. A devastating tsunami after a strong 9.0-magnitude earth-quake had destroyed the power plant in March 2011 spreading large scale radiation in the region.
Japan’s NHK television reported Tuesday that Radioactive cesium levels in one of the observation wells at the Fukushima Daiichi nuclear plant in north-east Japan have jumped up 90 times.
NHK cited a report from Tokyo Electric Power Company, the plant’s operator, saying that “9,000 becquerels of cesium 134 and 18,000 becquerels of cesium 137 per liter of water at a well between the No. 2 reactor building and the sea” were recorded on Monday.
TEPCO experts have been unable so far to determine the cause of the sudden rise in cesium levels, or to assess the impact of the spike on the nearby ocean.
In addition, seawater in the port next to the Fukushima plant has been showing increasing levels of radioactive tritium since May, the company said.
The March 2011 massive earth-quake and the ensuing tsunami, had claimed over 15,000 lives and triggered a number of explosions at the Fukushima nuclear plant.
The tsunami caused a partial meltdown at three of the nuclear plant’s reactors. Radiation leaked into the atmosphere, soil and seawater, making the accident the world's worst nuclear disaster after Chernobyl.
Japan will need at least 40 years to recover fully from the nuclear catastrophe, scientists say.
Some 315,000 victims are still living in a temporary housing unable to return to their houses in the plant’s vicinity.
