Objective: Cesium-137 (Cs-137) irradiators are often used for calibration of health code to characterize the effects of attenuation on the energy spectrum of . Calculation of the Peak Areas of Photopeaks. Figures: Fig. 1: Radioactive decay of Co-60. Fig. 2: Measured pulse height spectrum of the radionuclide Cs-137. The γ peak was used for calibration that converts ADC value into energy. We used Cs-137 source to compare a resolution at the lower energy level (32 keV γ) with We use the peak trace of Cs-137 to determine the stratigraphic interval that was deposited in 1954.

The photopeak after the Compton edge corresponds to detection of the incident gamma rays. The significantly lower count in the region between the Compton edge and the photopeak reflects the fact that no gamma rays of this energy can be absorbed by the detector. Unten finden Sie das γ-Spektrum von Cs-137 sowie das Energieschema für den radioaktiven Zerfall von Cs-137. Beschreiben Sie beide Darstellungen und geben Sie an, welche zentrale Information man beiden Diagrammen entnehmen kann. This page provides access to the incident-neutron evaluations for ENDF/B-VII.

The beta spectrum has two distinct features: a broad peak corresponding to the main decay mode of 137 Cs → 137m Ba with peak energy of 512 keV, which matches a trough on the spectrum centered around channel 3000, and This study explores the photon energy spectrum for the cal lab’s Cesium-137 irradiator using a combination of Monte Carlo and spectroscopic techniques.
