Coincidence summing corrections for point and volume 152Eu sources

• The count rate equation system for 152Eu was formed by DMM method.
• Coincidence summing corrections and peak and total efficiencies for point and volume sources were determined.
• Obtained results were compared with ones calculated by using the GESPECOR 4.2 software.

In this article, the X-ray and gamma-ray coincidence summing effect in 152Eu is studied. Coincidence summing corrections and peak and total efficiencies of point and volume sources were determined using the direct matrices multiplication (DMM) method. The theoretically evaluated peak count rates were found to be in good agreement with the experimentally obtained values. Validation was performed by comparing the calculated efficiency curves and the corresponding correction factors with the results obtained using GESPECOR 4.2 software.
