The activity ratio of uranium in unknown samples and materials is a crucial signature tool for verification, assay, and tracking of their origin. This paper deals with using γ-ray spectrometric analysis and a new derived formula to calculate the 235U/238U activity ratio. Reference IAEA materials and a highly efficient calibrated HPGe spectrometer were used for the verification and validation of this equation and the results of assay. The calculated specific activities and 235U/238U activity ratios show very good agreement with the declared reference values, 0.046, with differences less than 2%. Natural origin samples were also investigated and assayed with the maximum deviation in the range 1.3–2.9%. Any potential deviation from the reference natural value, 0.046, in uranium samples could be precisely detected, identified, assessed, and quantified using the suggested system and equation.
