"Tokyo Electric Power Co. said radioactive water may still be leaking into the sea from the crippled Fukushima No. 1 nuclear power plant after enhanced levels of radioactive tritium were detected in the port area in front of the facility."
"The plant operator said June 24 it is investigating the matter with some urgency as the finding suggests that radioactive water, generated on the plant premises, may be leaking into the sea from the ground.
TEPCO said tritium levels of 1,100 becquerels per liter of seawater were recorded June 21 north of the water intakes for the No. 1, No. 2, No. 3 and No. 4 reactors in the port area.
The reading compares with 500 becquerels per liter measured on June 10. It was the highest concentration since the nuclear crisis began to unfurl in March 2011."
