gamma-ray spectrometry

[′gam·ə ‚rā spek′träm·ə·trē]
(nucleonics)
Determination of the energy distribution of gamma rays emitted by nuclei. Also known as gamma-ray spectroscopy.
In particular, a variation of neutron activation analysis in which the induced radiation from the sample is gamma rays instead of neutrons.
