━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ http://www.activistpost.com/2012/01/plutonium-from-fukushima-has-now.htmlFriday, January 6, 2012 Plutonium From Fukushima Has Now Circled The Planet Sayer Ji, Contributing Writer Activist Post A recently published study (http://www.greenmedinfo.com/article/aerosolized-plutonium-fukushima-has-been-detected-europe)in the Journal of Environmental Radioactivity confirms that the radioactive fallout from the Fukushima nuclear disaster reached Europe (Lithuania), and included plutonium, the most deadly manmade element (nanogram for nanogram) in existence.
According to the study's authors the radionuclide concentrations measured indicate there was "long-range air mass transport from Japan across the Pacific, the North America and the Atlantic Ocean to Central Europe as indicated by modelling." What this means is that every region under the jet stream -- which includes half of the planet north of its equator -- could have been exposed to some degree of plutonium fallout. This fact is all the more disturbing when we consider there is no such thing as a safe level, and that the harm (on the human scale of time) does not dissipate: the half life of plutonium-239 is 24,200 years, and that of uranium-238 is 4,460,000,000 years, which is older than our planet. In a past exposé, where we identified the likelihood of the occurrence we are now reporting on, we published Jet Stream radiation dispersion projections from Germany's EURAD system which showed that Radioiodine-131 and Cesium-137 were within detectable concentrations thousands of miles away from Fukushima within days after the event. This was, after all, a nuclear explosion (as occurred also at Chernobyl) producing extremely small particles moving at extremely high velocity, and not a hydrogen-based conflagration, which was erroneously reported to be the case in the first days following the disaster. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Abstract: Analyses of (131)I, (137)Cs and (134)Cs in airborne aerosols were carried out in daily samples in Vilnius, Lithuania after the Fukushima accident during the period of March-April, 2011. The activity concentrations of (131)I and (137)Cs ranged from 12 μBq/m(3) and 1.4 μBq/m(3) to 3700 μBq/m(3) and 1040 μBq/m(3), respectively. The activity concentration of (239,240)Pu in one aerosol sample collected from 23 March to 15 April, 2011 was found to be 44.5 nBq/m(3). The two maxima found in radionuclide concentrations were related to complicated long-range air mass transport from Japan across the Pacific, the North America and the Atlantic Ocean to Central Europe as indicated by modelling. HYSPLIT backward trajectories and meteorological data were applied for interpretation of activity variations of measured radionuclides observed at the site of investigation. (7)Be and (212)Pb activity concentrations and their ratios were used as tracers of vertical transport of air masses. Fukushima data were compared with the data obtained during the Chernobyl accident and in the post Chernobyl period. The activity concentrations of (131)I and (137)Cs were found to be by 4 orders of magnitude lower as compared to the Chernobyl accident. The activity ratio of (134)Cs/(137)Cs was around 1 with small variations only. The activity ratio of (238)Pu/(239,240)Pu in the aerosol sample was 1.2, indicating a presence of the spent fuel of different origin than that of the Chernobyl accident.
