In the Fukushima Disaster Zone with UCLA researchers, Mar 3, 2015: Four years after Fukushima disaster, some areas remain untouched, clocks recording the exact time that the tsunami swept through. Access is highly restricted but two UCLA researchers were recently given permission to document the disaster zone. — at 3:45 in — “With this study I think that’s what we’re trying to explore — is that once a nuclear catastrophe strikes, it’s not only affecting that local area, but also worldwide.”
Atmospheric dispersion of Iodine-131 released after the Fukushima event, by Giuseppe A. Marzo, ENEA (Italian National agency for new technologies, Energy and sustainable economic development), 2014: From March 12, 2011, a significant amount of radioactive material… discharged into the atmosphere… Total emission of 131I has been estimated in [128** petabecquerels (PBq)], while 133Xe, and 137Cs total emissions have been estimated in [15,300 PBq and 36.6 PBq], respectively. In this work the global atmospheric dispersion of 131I released by the Fukushima accident is carried out, focusing on this specific radionuclide due to its radiological relevance in terms of consequences on the human health… Figure 1 summarizes the simulation results. It illustrates the radioactivity concentration due to 131I released into the atmosphere at specific times and integrated over the total atmospheric column. Immediately after the initial release on March 12, the plume moved eastward reaching the United States west coast on [March 15 at 10:00p PST]
