TEPCO held a press conference late at night on March 28, and disclosed that plutonium was detected in the soil sampled on March 21 and 22 in Fukushima I Nuclear Power Plant.

Plutonium was not derived from the past open air nuclear weapons tests, and it was highly likely that it was released in the current accident, said TEPCO.
