The gamma spectra of Eu/sup 152/ and Eu/sup 154/ at 245 to 500 and 1450 to 2000 kev were studied with a magnetic gamma spectrometer. The ratio of Eu/ sup 154/ and Eu/sup 152/ was determined on the basis of the gamma quanta 1280(Eu/sup 154/) and 1411 (Fu/sup 152/)kev to be 0.21 plus or minus U.03. Energies and relative intensities for Eu/sup 152/ and Eu/sup 154/ are tabulated.

Eu 152 gamma spectrum

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. Gamma-ray characteristics Gamma rays are the highest-energy form of electromagnetic radiation, being physically the same all other

Therefore, in the spectrum being measured, there will be three peaks for each gamma energy.

The coincidence gamma spectrum was recorded simultaneously on a multichannel pulse-height analyser at the angles 270°, 180° and 90°, where the γ Gamma ray γ Annih. Annihilation radiation Σ Signifies weighted mean energies and intensities Gamma Emitters The following is a listing of selected (greater than 100 million electron volt or “MeV”) radionuclides, ordered by element, that emit gamma ray photons during radioactive decay. Each entry gives the radionuclide symbol (i.e., I-131), followed by the photon energy (in units of MeV), followed by the photon yield (i.e., probability per decay). True coincidence summing correction factors for Ba-133, Eu-152 and Sb-125 were determined experimentally for a small volume source and compared with correction factors obtained with three softwares (EFFTRAN-X, GESPECOR and VGSL).
