Uranium: Nuclear Friend Or Nuclear Foe

On Monday August 6, 1945 the U.S. Bomber Enola Gay flew over the
Japanese city of Hiroshima. Seconds later a metallic projectile fell
towards its target. In a blinding flash the world felt the power of a new
age, the nuclear age.
The study of radiation that would eventually lead to these uranium
weapons began in 1798. It was in this year that the german chemist Martin
Heinrich Klaproth identified the element uranium. Uranium was not isolated
in a metallic state until 1841. The radioactive properties of uranium were
first discovered in 1896 when a French physicist Antoine Henti Becquerel
studied the properties of uranyl sulfate.
Although science found uranium in 1789, the study of ...

deaths were due
to lung cancer. But with their scientific knowledge the doctors could only
assume that the deaths were caused by the inhalation of arsenic. Later
studies between 1900 and 1940 found that the deaths were caused by
radiation in the mines.
The radiation the miners were exposed to would later be identified
as uranium. Uranium is a natural occurring element, it has a atomic count
of 92. Uranium is easily identified by its properties. Uranium melts at
about 1132C, boils at about 3818C, and has a specific gravity of 19.05 at
25C. Uranium has three crystalline forms, of which the one that forms at
about 770C is malleable and ductile. Uranium is soluble in hydrochloric
acids and nitric acids, but not in alkalies.
Uranium never occurs naturally in the free state but is found as an
oxide or complex salt in minerals such as pitchblende and carnotite. It has
an average concentration in the earths crust of about 2 parts per million,
and ranks 48th among the natural ...

of energy and the presence of
barium were caused by the splitting of uranium atoms. It was at that moment
that the world was first introduced to man controlled nuclear power.
After the successful splitting of an atom, many nations set to work
to find a way to produce and extract energy from the reaction. The first
generation of electric power from nuclear power was achieved at a reactor
testing center in Arco, Idaho. This early generating plant utilized a form
of nuclear energy call fission. In this process uranium-235's nuclei is
split open when struck by an sub-atomic particle called a neutron. This
breaking open releases two or three neutrons which then split open ...
