Gamma Spectroscopy

 

one of the branches of nuclear spectroscopy; deals with the study of gamma-radiation spectra and the various properties of the excited states of atomic nuclei whose decay is accompanied by the emission of gamma quanta. The task of gamma spectroscopy, like alpha and beta spectroscopy, it to investigate the structure of atomic nuclei. Gamma spectroscopy also analyzes the gamma radiation produced by radioactive decay and nuclear reactions. The gamma-radiation spectra—that is, the energy distribution of the emitted radiation—are measured with gamma spectrometers.

Samples were then separated by tissue and species, homogenized with a commercial food processor, and placed into a 500 mL or 1000 mL high-density polyethylene Marinelli beaker (Gamma Associates) designed for direct gamma spectroscopy. The beakers were labeled, sealed, frozen, and shipped to the Environmental Sciences Division, Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee.
