Now the Fukushima-1 nuclear plant officials are acknowledging, via CNN at noon, that they discovered plutonium in the soil a week ago outside the reactor buildings. There is no explanation how plutonium (a highly toxic long-lived radioactive element) might have been deposited there but there had to be some kind of break in Unit 3, the other reactor at the complex that uses a composite plutonium-Uranium fuel. So was it from a breach in the spent fuel pool wall or the reactor primary containment? And was it borne out of the reactor building in one of the hydrogen explosions?
