IRSN (France) — Initial analyses of the accident and its consequences (pdf): [E]stimates of the radioactivity released for [plutonium and other transuranium elements] remain rough due to the lack of a sufficient body of measurements and information on the actual condition of the damaged reactors. [...] Their presence in the environment due to the accident has not been easy to detect [...] neptunium-239 [...] in the village of Iitate proves without doubt that transuranium radionuclides were released by the Fukushima accident. This is also confirmed by the interpretation of certain results of plutonium measurements taken in the soils northwest of the Fukushima Dai-ichi site [...] all these values were obtained at points located within the main fallout zone extending to the northwest makes it possible to attribute this plutonium to releases from reactor 2 after its containment was damaged by the hydrogen explosion on March 15 […] The highest values for 238Pu were measured more than 20 km from the Fukushima Dai-ichi plant, at points 3 and 4 northwest of Namie and south of Iitate.
ABC (Australia), Jan. 29, 2014 (at 16:00 in): A TV appearance by Professor Narabayashia member of the Nuclear Safety Commission did nothing to help dispel our doubts either. He said that up to 32 grams of plutonium could be ingested with food without danger of death. If breathed plutonium was only deadly from 10 mg upwards. Independent scientists assume that even 1/1,000,000 of a gram can trigger lung cancer.
