Applications of relative and internal monostandard NAA methods for analysis of alloys: as a part of chemical quality control exercise

INAA using relative as well as internal monostandard methods has been applied for the major, minor and trace element determination of various alloys namely Nimonic alloy, Lead-Bismuth alloy and Zircaloys. The elements determined include, In, Sn, W, Mn, Sb and Ag in lead-bismuth alloy, Ni, Ti, Al, V and Mn in Nimonic alloy and In, Sn, Mn, Cl, Hf, Ta, Cr, Fe, Ni and Zr in zircaloys. The results were compared with the results obtained by ICP-AES. (author)
