The source energy effect on the quality of counting profile obtained using gamma ray scanning technique was investigated. A lab-scale tray type column (one-pass tray type with 51 cm diameter) along with a 1×1 inch NaI(Tl) has been applied to investigate the source energy effect. MCNPX Monte Carlo code was used to simulate the column in normal and abnormal operating conditions. Cs-137 and Co-60 sources were used to investigate the source energy effect. The simulation results of the column scanning were validated by experimental measurement results. Based on the outcomes, Cs-137 leads to a better statistics and the foaming defect is better distinguished using Cs-137 compared with Co-60.
