dc.description.abstractIn this study, we combine ITRAX Core Scanning, Grain size and Radiochemistry (Pb-210, Cs-137 and Pu-239/240) techniques to investigate pollution and age of sedimentation in Mill Creek. The creek drains a catchment containing the Lucas Heights Waste Management facility, the Lucas Heights Science precinct and the Little Forest Burial Ground. The ITRAX core scanner non-destructively collects optical and X-radiographic images, and provides high-resolution elemental profiles that are invaluable for guiding sample selection for further detailed sampling. The core from the creek was first scanned on the ITRAX core scanner and further sampled for the other techniques. The chronology for the sediment core was developed using Pb-210, Ra-226 and Cs-137 analysis.en_AU
