Abstract

Monte Carlo simulations have been performed of the decay of a(198) Au solid source within a 4πβ-γ coincidence detector. Calculations of the proportional counter efficiency to both β and γ emissions are simulated. A comparison of results obtained using the MCNP-5 and Geant4 simulation packages indicates that Geant4 better evaluates the K correction to the coincidence equation than MCNP-5 predictions. This difference can be accounted for in terms of how the codes handle the physical interactions occurring in the foil and surrounds. © 2008, Institute of Electrical and Electronics Engineers (IEEE)
