Abstract : A technique is developed for the analysis of trace metallic contaminants in jet fuels by neutron activation. It is designed for routine use at the Air Force Nuclear Engineering Test Facility. Jet fuel, grade JP-6 is exposed to a thermal neutron flux of 5 x 10 to the 12th power neutrons per sq cm-sec, and analyzed with a gamma-ray spectrometer, Aluminum, Copper, Manganese, and Magnesium are detected. The Copper results indicate 101.7 nanograms per ml of fuel, reproducible to 9.5%, and Manganese indicates 2.91 nanograms/ml, reproducible to 11.5%. Magnesium and Aluminum results are not reproducible. Standard curves for each element are developed, which graph weight of element as a function of net activity under the photopeak. (Author)
