Americium is an important actinide element having versatile applications based on its alpha and gamma emissions. Multi-element
determination of radioactive samples using ICP-AES technique may be affected by the presence of americium due to its rich
emission spectra. With a view to characterize plutonium based fuels containing americium for trace metals by ICP-AES technique
accurately, a high purity 241Am (using a separation procedure developed in our laboratory) was prepared. To ascertain its chemical purity it is essential
to determine its impurity contents accurately. Instrumental neutron activation analysis (INAA), being a sensitive multi-elemental
technique, was employed to determine the concentrations of impurities in purified 241Am. Detection limits for the common elements and rare earth elements have also been determined. Comparison is made with the
analytical data obtained by the ICP-AES method.
