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.
