…showed last 75 words of 157 total…numbers. Thorium 232 happens naturally and is the first
member of the radioactive-decay series.It is currently being
studied as a potential atomic-fuel source for the future,
which is called the thorium-uranium fuel cycle.It is
hopefully going to be a substitute for the uranium-plutonium
fuel cycle.Thorium metal is used im magnesium alloys and as
a stabilizing component of electronic tubes. Thorium oxide
is used in light filiments and electrodes and also in a
catalyst.
