» Strontium and Tritium found in well water at Fukushima No.1 plant

Tokyo Electric Power Co. said on June 19th that it has detected very high radioactivity levels in groundwater from an observation well at its Fukushima No.1 nuclear power plant.

In the water sampled May 24, the strontium 90 level stood at 1,000 becquerels per liter, about 30 times as high as the maximum allowable standard, and the toritium level at 500,000 becquerels, some eight times higher, it said.

The company plans to dig four more wells around the observation well to check any spread of radioactive contaminated water and improve the seawall to prevent contaminated water from flowing into the sea.
