In this work, three different procedures (direct gamma-ray spectroscopy, indirect gamma-ray spectroscopy and gamma-gamma coincident spectroscopy) are employed in the determination of the amount of 235U in a well-known enriched-Uranium sample, and all three are discussed as possible alternatives to determine 235U in environmental samples. The results show that the three methods give similar results, although these results are all ~30% below the expected value.
