Abstract: We present new results on neutron and gamma-ray pulse-height distributions measured with liquid scintillators from five plutonium-oxide samples of varying mass and burnup and a Cf-252 isotopic source. We show that the analysis of the pulse-height distributions can be used to easily distinguish the fissile material (plutonium oxide) from the Cf-252 source. Moreover, the slope of the measured pulse-height distributions can be analyzed to distinguish the burnup of the samples, independently of their mass. Finally, the measurement scenarios are modeled using the MCNP-PoliMi code and good agreement is observed between the measured and simulated pulse-height distributions.
