Survey of standardization methods of Instrumental Neutron Activation Analysis: A review.

Abstract

The quest for a versatile standardization method for Instrumental Neutron Activation Analysis Technique has been the major driving force behind many research works for the past few decades. The key factor is the desire to overcome the limitation of dependence on multi-elemental standards without sacrificing analytical accuracy and experimental simplicity. Appraisal of the different approaches towards standardization of Neutron Activation Analysis has been carried out; re-visiting the strengths and weaknesses of each standardization method. k0-standardization method is proposed to be the most suitable for its robustness and for providing remedy to the drawbacks in other methods. The basic principle of Neutron Activation Analysis and the superior qualities of k0-standardization has been reviewed.
