The Detective X Ultra High Resolution HPGe Radioisotope Identification Device by ORTEC is known in the industry as the "The Gold Standard" for nuclear threat detection and identification.
Abstract Time counting optimization in gamma-ray spectrometry was established using four HPGe detectors and four counting geometries. Deionized water samples with a mixed radioactive solution of 133Ba, 134Cs, 106Ru, 137Cs, 65Zn, and 60Co were prepared in volume from 0.1 to 3 L, and measured three times, for all detection systems,
Naturally occurring barium (56 Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001.
Penpoint marker sources: 57 Co is incorporated in ceramic matrix and sealed in beryllium capsule with alluminium alloy holder. The source is supplied with brass cap to transport and storage.

Gamma ray spectroscopy is commonly incorporated in the physics curriculum as part of a modern physics or advanced laboratory course, with Cs-137, Am-241, Co-57, and Na-22 typically used as the gamma-emitters. These isotopes are in excited states, and gamma rays with characteristic energy spectra are emitted when they return to the ground state. The
