Notes
G. Fusion
Fusion is the process of two nuclei joining
together. The energy source in most stars is
nuclear fusion of hydrogen isotopes.
SOURCES AND USES OF TRITIUM
How is tritium produced and what is it used for?
A. Sources of Tritium
There are three primary sources of tritium in
our environment. Tritium is present in our
environment from both man-made and natural
sources as discussed below. Natural tritium is
indistinguishable from man-made tritium.
1.
Natural Sources
Tritium occurs naturally. It is formed by
the reactions between cosmic rays and the
nitrogen in the upper atmosphere.
Nitrogen makes up 80% of the earths
atmosphere.
Cosmic rays generate approximately 4
million curies of tritium per year. With
tritium being continually produced and at
the same time decaying, the natural
tritium in our environment is about 70
million curies.
