Yokohama, Oct. 15 — Mochizuki of the Fukushima Diary website is reporting on a June 2011 document that has been “leaked on the internet” which reveals that Plutonium-238, -239, -240, and -241 were released “to the air” from Fukushima Daiichi during the first 100 hours after the earthquake.
The amount of plutonium released is said to be 120 billion Becquerels.
It also states there was a release of 7.6 trillion Becquerels of Neptunium-239. As neptunium-239 decays, it becomes plutonium-239. (SOURCE)
Mochizuki says this report was made by Tepco for a press conference on June 6 and the media knew and “kept concealing the risk for 7 months and kept people exposed”.

UPDATE: Mochizuki has updated his post. It appears the plutonium figures are now 1.2 trillion Becquerels, 10 times higher than originally reported.
