Abstrakt: Three Egyptian phosphate reference materials (S1, S2 and S3) were investigated using short-term activation analysis. The precision of the determination of Dy, Sc, Gd, Yb, Mg, V, F, Al, Mn, and Ca by this method ranged from 2 to 5% due to the homogeneity factor. Another 11 elements were determined by NAA using medium and long-lived nuclides. Most results were in good agreement with the recommended values. The values of Dy and Gd are reported.
