Na-22 ⇒ Ne-22 + positron + electron neutrino + energy. Because beta particles share their energy with an antineutrino or neutrino, the beta energy spectrum is 

The large peak at the far right is called the photopeak and arises when all the gamma ray energy is deposited in the scintillator. Note the 5-10% width of this The gamma spectrum has two significant peaks, one at 1173.2 keV and another at 1332.5 keV. Good scintillation detectors should have adequate resolution to separate the two peaks. For HPGe detectors, these peaks are perfectly separated. As can be seen from the figure, there are two gamma ray photopeaks. Gamma Ray Dose Constants.

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.

annihilation gamma. This is a special spectrum, it was taken with PRA 5.0 using two sodium iodide detectors, in coincidence counting mode, to detect the annihilation gammas that are produced when 22Na undergoes beta+ decay. The positron instantly annihilates with an electron, producing two 511 keV gammas at a 180˚ angle.

The radioactive isotope Na-22 decays through β+ emission. Figure 10.2 shows the decay scheme of Na-22. Figure 10.2. Decay scheme of Na-22. The decay scheme shows that the β+ emission is in 99.94 % of the decays followed by a gamma ray with an energy Eγ1 = 1.27 MeV. The emitted positron will immediately
