Coincidence Summing Factor Calculation for Volumetric γ-ray Sources Using Geant4 Simulation

Abstract

Geant4 simulation was applied to correct the coincidence summing (CS) effect in detecting a volumetric γ-ray sources, and this technique was applied to a152Eu standard sources. The radioactive sources were a liquid cylindrical, rectangular, and Marinelli beaker shapes of different volume for each one. Radionuclide track (RT) including coincidence summing and monoenergetic track without coincidence summing. The results obtained from two approaches compared with the experimental data and the modified KORSUM code for cylindrical γ-ray source. The comparison showed that the adopted method in this investigation is useful for coincidence summing corrections for a voluminous γ-ray sources.Moreover, this technique requires far less computation time than the techniques that depend on the calculation of total efficiency.

Experimental Study on the Radiation Shielding Performance of B2O3-SiO2-TeO2-Bi2O3-ZnO-BaO Glass Systems Containing Europium (III) Oxide

“…Radiation shielding study.-The prepared BiTeEu-glass samples were measured by experimental technique using a HPGe detector and three radioactive point sources covering low, medium and high energies.
