Comparable uranium sensitivities and detection limits can be obtained by either energy- or wavelength-dispersive x-ray fluorescence (XRF) analysis of L x-rays, and by wavelength-dispersive analysis of M x-rays. XRF methods are more sensitive than 252Cf neutron-induced γ-ray analysis or direct photon analysis of rapid-equilibrium uranium daughters. A laboratory method is demonstrated for quantitative uranium determination in unknown geological matrices without using ore standards.
