TEPCO to cleanup radioactive debris from n-plant by July

TEPCO has created a map of radiation levels as part of its removal of radioactive debris at the crippled Fukushima nuclear power plant, the TV channel said.

According to TEPCO, highly radioactive debris is lying in some areas of the compound. Radioactivity of 900 millisieverts per hour was detected on a concrete fragment near the third reactor on Wednesday, the TV channel said.

The company has said, however, that it hasn't decided yet on places and methods of disposing of removed debris.

The 9.0-magnitude earthquake and subsequent 15-metre tsunami March 11 triggered a crisis at Fukushima nuclear plant, which is being rated at the same level as the 1986 Chernobyl disaster.

Fukushima's operator TEPCO has since been struggling to stop radioactive leaks from the plant's crippled reactors. Almost 80,000 people living within the evacuation zone were forced to flee their homes.
