Abstract: This report describes the use of Sodium Iodide (NaI) scintillation detectors, for the detection of Depleted Uranium (DU) at long ranges with short integration times. Experimental data was taken by setting up the NaI detector in front of a 16 kg sample of DU and looking at the variations in the observed decay spectrum over different distances, integration times, and detector orientation. Also, using a known efficiency equation for NaI detectors, an analytical comparison of measured to calculated data was performed. This report is meant to serve as a basis for future DU detection experiments by providing base measurements and predictions for further studies.
