Casimiro S. Munita, Michael D. Glascock and Roberto Hazenfratz
An overview of neutron activation analysis (NAA) and some applications
for this technique are provided. The fundamentals of the various methods of NAA
(INAA, relative, k0, large sample, prompt gamma charge particles, cyclic, molecular
and radiochemical NAA, gamma-gamma coincidence NAA) are discussed in order to
describe the most important scientific and technical aspects. Several problems
associated with the technique are pointed out and briefly discussed. Emphasis is laid on
the advantages of this technique for the determination of trace elements in geological,
biological and environmental samples as an alternative analytical technique where
other methods would not be the best choice. The role of NAA in quality assurance and
quality control is also described.
