Just In: “Nuclear fuel fragments” from Fukushima found in Europe — 10,000+ kilometers from reactors — Study: Plume “directly from N. America” — Hot particles a “significant part” radioactive releases — Quickly spread over entire hemisphere — Film shows core material on Norway air filter (PHOTO)
Atmospheric Chemistry and Physics Discussions, Atmospheric removal times of aerosol-bound radionuclides, May 2012: Hot particles (e.g., fragments of the nuclear fuel) were present in the FD-NPP plume.http://enenews.com/wp-content/upload....-06-12.34.jpg

Elsevier (academic publisher) — Fukushima Accident: Radioactivity Impact on the Environment, 2013: Paatero et al. (2012) estimated that a significant part of the Fukushima-derived radioactivity is in hot particles from autoradiogram of a filter sample from 1 to 4 April 2011 at Mt. Zeppelin, Ny-Alesund, Svalbard.
Poster for Alaska Marine Science Symposium (Arctic Ocean and Bering Sea/Aleutian Islands), Jan. 20, 2014: Exposure to fallout while on ice in 2011 [...] Models suggest pinnipeds may have been exposed while on ice to the following: [...] Hot particles, nuclear fuel fragments, were detected in air samples taken in Svalbard, Norway (Paatero et al. 2012).http://enenews.com/wp-content/uploads/2014/05/sval.jpg
(Paatero et al. 2012) Airborne fission products in the High Arctic after the Fukushima nuclear accident: The plume arriving in Svalbard did not come from Europe but directly from North America [...] [Hot particles are] either fragments of the nuclear fuel or particles formed by the interactions between condensed radionuclides, nuclear fuel, and structural materials of the reactor [...] a significant part of the activity related to Fukushima was in hot particles. So far the authors are not aware of any other reports concerning hot particles from the Fukushima accident. [...] radionuclides emitted into the atmosphere were quickly dispersed around practically the whole northern hemisphere within a couple of weeks.
