|The identification of a source, especially if environmental,
can be a long and tedious task. The quickest procedure is shown here.
- Always select a high intensity gamma peak at the high energy end of
the spectrum. At this energy there is less ambiguity and so peaks can
be identified easier than from lower energies.
- Consult a table of isotopes so that identification can be performed.
- The isotope associated with an energy can be confirmed by checking
the associated gamma energies with that isotope and seeing if that
peak is found in the spectrum.
- Now repeat the above by selecting the next intense unidentified
gamma ray and continue until all possible peaks are identified.
