Abstract

A standardization method for NAA has been developed based on the activation equation and on isotope-related k i -values that are composite nuclear constants. This approach combines the simplicity of the absolute methods with nearly the same accuracy as that obtained by the relative ones. The k i -constants are calculated from the well measured k 0-factors and the neutron flux is determined as with the k 0-method. A computer program was developed for the determination of the neutron flux parameters and the concentration of the trace element. These calculations start with the measured activity of the radionuclides.
