Radioactive cesium levels 90% higher in Fukushima groundwater

Fukushima-reactor-6Fukushima Groundwater Shows Record Radiation Levels HUFFINGTON POST, Reuters   07/09/2013 “……SITUATION WORSENS Tokyo Electric Power Co, the operator of the Fukushima station, hit by the March 2011 earthquake and tsunami, said that an observation well between the damaged reactor No. 2 and the sea showed levels of radioactive caesium-134 were 90 times higher on Monday than they had been the previous Friday.

water-radiationTokyo Electric, also known as Tepco, said it detected caesium-134 at 9,000 becquerels per litre, 150 times above Japan’s safety standard. A becquerel is a measure of the release of radioactive energy. The reading for caesium-137, with a half life of 30 years, was some 85 times higher than it had been three days earlier.

The latest findings, 25 metres from the sea, come a month after Tepco detected radioactive caesium in groundwater flowing into its wrecked plant far from the sea on elevated ground. The level of caesium found in June was much lower than the amount announced on Tuesday.

The spike, combined with recent discoveries of high levels of radioactive elements like tritium and strontium, suggest that contaminated water is spreading toward the sea side of the plant from the reactors sitting on higher ground…..

The operator has been flushing water over the three reactors to keep them cool for more than two years, but contaminated water has been building up at the rate of an an Olympic-size swimming pool per week. In April, Tepco warned it may run out of space to store the water and asked for approval to channel what it has described groundwater with low levels of radiation around the plant and to the sea through a “bypass”. Local fishermen oppose the proposal….. http://www.huffingtonpost.com/2013/07/09/fukushima-groundwater-radiation_n_3565767.html
