Gamma-ray Spectrometry Catalog
For more than three decades, Idaho National Laboratory (INL) has been a leader in the development of radiation detectors, nuclear metrology, and the application of -ray spectrometry to radiation measurement. This capability represents a world-class resource in radiation measurement technique and system design. It has produced many significant advances in radiation detectors and electronics as well as a vast quantity of scientific data related to radiation measurement technology.
Beginning with the startup of the world’s first high-flux beam reactor, Materials Test Reactor (MTR), INL has pioneered the development of -ray spectrometry for use in basic nuclear research and a variety of disciplines using radioisotopes and other radiation sources. In the early 1950’s, a program was instituted to make the technique a precise laboratory tool. Standards were established for detectors and nuclear electronics to promote the production of commercial laboratory spectrometers. It was also necessary to produce a comprehensive collection of standard detector response functions for individual radio nuclides to permit the use of gamma-ray spectrometers for identification of radioisotopes present in radiation sources. This led to the publication of standard measurement methodology and a set of Gamma-Ray Spectrum Catalogues. These publications, which established standards for detector systems, experimental methods and reference spectra for both NaI (Tl) scintillation detectors and Ge(Li) – Si( Li) semiconductor devices, became standard reference works, distributed worldwide. Over 40,000 copies have been distributed by the Office of Science and Technical Information (OSTI). INL has converted this large volume of data to a format which is consistent with current information technology and meets the needs of the scientific community.

Note: “_2” or “_N” right after mass number indicates the second data or the new measurement taken with a HPGe detector, respectively.
The INL’s Gamma-ray Spectrum Catalogue compiles spectra from various detector types and presents these spectra with decay schemes and data tables based on the latest Evaluated Nuclear Structure Data File (ENSDF) data. It includes Ge spectra and decay data as well as available spectra acquired for the original NaI(Tl) and Ge(Li) Catalogues. All information is documented by the spectra acquisition date and the ENSDF download date.
Progeny peaks are colored red or blue, as are the parent radioactinide peaks. The radionuclide symbols of the progeny peaks are placed in parentheses by the labeled peak and colored brown. The decay schemes and gamma-ray energy and emission probability tables associated with the parent and progeny are given for each member of the decay chain.
Spectral content and shape is dependent on the “source age” when progeny grow-in is occurring at the time of spectral acquisition. Source age is defined as the calculated time since the parent activity could be considered free of any progeny or the actual (measured) time since the parent was chemically separated from all of its progeny. Whenever a meaningful source age can be measured or calculated, it is given in the legend. Spectra with different source ages and taken on different types and sizes of detectors are included in the Gamma-ray Spectrum Catalogue.
The spectral data from the original NaI(Tl) and Ge(Li) Catalogues have been incorporated for different uses and to allow comparisons of detector type, size, and source age.
