The observed β + spectrum of Na 22 has a statistical shape. The Fierz term b is obviously zero; the 0) x 10 -3 This is desired for gamma-ray spectroscopy because we are interested in knowing the energies of the various gamma-rays that are emitted by a source. In Figure 3.3, we see what the ideal photopeak created by mono-energetic gamma-rays of a single energy looks like. 3.1.2 Compton Scattering The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample.

Na 22 gamma spectrum

Sum. E X P E R I M E N T 1. Figure 1.1 Gamma Spectrum of. 22. Na source with a 3.8 cm x 2.5 cm NaI(Tl) scintillation detector. Energy Calibration. 22. Na is a unique isotope since its positive beta decay is followed by two gamma rays far away from each other.

Fig. 13.2 shows a typical gamma-ray spectrum for 22 Na obtained with a NaI(Tl) detector. The 0.511 MeV peak will usually be substantially more intense than the 1.274 MeV peak, due primarily to the detector efficiency differences at the two energies (see Experiment 3), and the fact that two 511-keV photons are generated for each positron decay. Spectrum β+ Sodium 22 (22 Na) The isotope Na-22 decays (in 99.95% of cases) with a half-life of 2.6 years, by positron emission or electron capture to the first excited state of 22 Ne 1,274 MeV (which then relaxes by emitting gamma photon). The positrons emitted by the source annihilate inside the material that acts as a support to the source Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics. Most radioactive sources produce gamma rays, which are of various energies and intensities.
