Abstract

Abstract: A simulation technique was developed for the extrapolation technique in 4πβ–γ coincidence counting method. Simultaneous emissions of β and γ rays were calculated using EGS5 code to obtain coincidence counting between both β and γ channels. The simulated extrapolation curves were compared with experimental data obtained with 134 Cs measurements using a plastic scintillator in the β channel. The variation of the extrapolation curves with γ-gate configuration was investigated by the simulation technique. Highlights: Simulation of 4πβ–γ coincidence set-up using EGS5. Extrapolation curve variations due to γ-gate configuration, β-counting efficiency. To decide the best function for the extrapolation and improve its uncertainty.
