Using this information, the 8 Apr 2019 The screen shown below refers to the isotope Cesium 134. Europium 152. There are 35 radioactive isotopes of Europium, of which the most 21 Apr 2018 Spatial Imaging of Low-Energy Gamma-Radiation. Sources.
11 Resolution and efficiency After studying the peaks of the energy spectrum obtained in gamma ray spectrometry for Eu-152 source, we now analyze some data to find the γ Gamma ray γ Annih. Annihilation radiation Σ Signifies weighted mean energies and intensities Intensity . Values are given in percent. The format used for the uncertainties in the listed values can be illustrated by the following examples: 1.2 56 = 1.2 ± 5.6 1.23 56 = 1.23 ± 0.56 References [1] PTB-6.11-97-1, Braunschweig, Oktober 1997 When Eu-151 captures a neutron from, say, a nuclear explosion, it turns into Eu-152. That’s a great way to estimate the neutron fluence (which is neutron flux integrated over time).
Thorium 232. The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks. Detectors smaller than 2" x 2" may have difficulty seeing the higher end gammas, which means you are only seeingt part of the spectrum.
