A recently published study 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 fall-out; a fact that 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.
