Gamma-ray spectroscopy is the qualitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics. Gamma-ray spectrometry , on the other hand, is the method used to acquire a quantitative spectrum measurement.
A gamma-ray spectrometer (GRS) is an instrument for measuring the distribution (or spectrum—see figure) of the intensity of gamma radiation versus the energy of each photon. The study and analysis of gamma-ray spectra for scientific and technical use is called gamma spectroscopy , and gamma-ray spectrometers are the instruments which observe ...
SPECT image (bone tracer) of a mouse MIP Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1]
The technique of measuring the gamma radiation with good efficiency is known as total absorption spectroscopy. The pandemonium effect concerns the difficulty in using high resolution detectors in beta decay experiments, to construct a complex level scheme.
A near-hollow sample of trinitite backlit to show light passing through the material Levels of radioactivity in the trinity glass at the time of explosion from two different samples as measured by gamma spectroscopy on lumps of the glass [21] The chaotic nature of trinitite's creation has resulted in variations in both structure and composition ...
Gamma spectroscopy is the study of the energetic transitions in atomic nuclei, which are generally associated with the absorption or emission of gamma rays. As in optical spectroscopy (see Franck–Condon effect) the absorption of gamma rays by a nucleus is especially likely (i.e., peaks in a "resonance") when the energy of the gamma ray is the ...

Annihilation radiation is a term used in Gamma spectroscopy for the photon radiation produced when a particle and its antiparticle collide and annihilate. Most commonly, this refers to 511-k eV photons produced by an electron interacting with a positron . [ 1 ]
