A detection system was designed with MCNPX-PoliMi to measure induced fission neutrons from U-235 and U-238 using active interrogation. Measurements were then performed with this system at the joint Research Centre in Ispra, Italy on low enriched uranium samples. Liquid scintillators measured induced Fission neutrons to characterize the samples in terms of their uranium mass and enrichment. Results are presented to investigate and support the use of organic liquid scintillators with active interrogation techniques to characterize uranium containing materials.
