from the US National Oceanic and Atmospheric Administration have
discovered what they claim is an atmospheric aerosol particle
enriched with the uranium which is used in nuclear fuel and
"highly unusual aerosol particle containing a very small amount
of enriched uranium" was tracked at an altitude
of seven kilometers above Alaska's Aleutian Islands,
according to a US National Oceanic and Atmospheric
Administration (NOAA) study published bythe
Journal of Environmental Radioactivity.
scientists underscored that the particle with the enriched
uranium-235 was spotted for the first time in twenty
years of observations. The uranium-235 is
specifically used for making nuclear fuel and bombs.
of wind trajectories and particle dispersion model results
show that the particle could have originated from a variety
of areas across Asia," the study said, citing China,
Japan and North Korea.
that the particle was detected in August 2016, it excludes
the disaster at the Fukushima nuclear power plant
in 2011 as a possible source.
in the dark about the origin of this particle,
researchers suggested that it is "definitely not from a
of the main motivations of this paper is to see
if somebody who knows more about uranium than any
of us would understand the source of the particle,"
NOAA scientist Dan Murphy toldGizmodo.
the same time, he said that it's too early to jump
to any conclusions about possible atmospheric
radiation caused by this particle because "it's not a
significant amount of radioactive debris by itself."
