Japan says plutonium found at Fukushima
TEPCO vice-president Sakae Muto told journalists at the company's latest briefing that test results showing the plutonium came from samples taken a week ago.
It was the latest bad news from the plant, where evidence of radiation has been mounting and engineers face a protracted battle to control reactors damaged by an earthquake and tsunami on March 11.
