TEPCO admits highly radioactive water from tank leaked into Pacific Ocean
The operator of Japan's crippled nuclear power plant has admitted that highly radioactive water leaking from a tank at Fukushima is thought to have seeped into the Pacific Ocean.
In a statement Wednesday, TEPCO said about half of the 3-hundred tons of leaked contaminated water was absorbed into the ground, but that six millisieverts per hour of radiation was measured inside a nearby drain, meaning some water likely spilled into the sea.
The country's nuclear agency raised further concerns that more tanks at the plant may be letting out radioactive water after they were built hastily following the 2011 disaster.
Earlier, the agency said it would bump up the level of crisis two notches to three on an international scale for radiological releases.
The International Atomic Energy Agency is observing the current crisis "seriously," and has offered to help when needed.
