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)

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).

(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.
