The report showed that levels of Plutonium 238 had been measured at 0.21 becquerels per kilogram, where before levels had remained either Non-Detect, or under 0.06 becquerels per kilogram according to date from the Ministry of Education, Culture, Sports, Science, and Technology. Prior to the Fukushima Daiichi nuclear disaster, Plutonium 238 had not been detected off short of the nuclear power plant, and the densities of Plutonium 239 and Plutonium 240 were over double what they were before. Plutonium 239 and Plutonium 240 were found to be around 1.2 becquerels per kilogram, significantly greater than previous measurement values in the sea near Fukushima Daiichi (0.17-0.56 becquerels per kilogram).

F'Shima is a long running Nuclear Power=Plant
and i am sure we will see this "Traces" everywhere
and in every sing US-American NPP,
this is not a Evidence that all this Stuff is gone!

The same for UNIT 2., afaik only one Reactor (Nr. 1.)
is fully molten but they estimate that Nr. 2 is only
partial molten, means that the Heat source must be
in the Reactor Pressure Vessel and not in the Torus!
