Building-up a code for the purpose of TRUE coincidence summing correction in gamma-ray spectrometry with EGS4

In the presented study, a code was created for the purpose of true coincidence summing (TCS) correction factors for 134Cs. The created code was implemented in EGS4 Monte Carlo simulation package. TCS factors were determined for nine different energies for different detector–source geometries. The ca...

Description
Summary:In the presented study, a code was created for the purpose of true coincidence summing (TCS) correction factors for 134Cs. The created code was implemented in EGS4 Monte Carlo simulation package. TCS factors were determined for nine different energies for different detector–source geometries. The calculated results were successfully validated by an empirical method using a point 134Cs radioactive source and a p-type HPGe detector having 55% relative efficiency. Although the code created gives TCS factors only for 134Cs, the technique presented can be used to obtain the factors for any radionuclide used in gamma-ray spectrometry. •A code was created for the purpose of true coincidence summing correction for 134Cs.•The created code was implemented in EGS4 for calculations.•Correction factors were determined for nine different energies using an HPGe detector.•Different source–detector distances were considered.•The calculated results were successfully validated by an empirical method.
