| Radiation from Fukushima Plant "Measured Globally" and Blanketed Entire Northern Hemisphere
US states hit with "extremely large peaks" of Fukushima radioactive material – "Significant amount" of plutonium released for months – Radioactivity from plant "measured globally" and blanketed entire Northern Hemisphere The Fukushima Daiichi nuclear disaster has been the second most serious crisis of a nuclear power plant in the human history[*]. The release period lasted over two months emitting a significant amount of radioiodine, radioxenon and radiocaesium as well as other isotopes such as plutonium. Besides the local to regional scale impacts of soil and water pollution, isotopes released into the atmosphere could be measured globally. Total atmospheric release was estimated to be 14000–15300 PBq of radioxenon and 340–800 PBq of other isotopes. The radioactive plume in the atmosphere moved towards the Pacific, reached North America in five days and Europe in eight days… Fukushima-derived radioiodine and radiocaesium could be identified in the entire Northern Hemisphere… The zonal
