A general formula for nuclear activation and decay is presented. Besides decay processes, it deals with burn-up and successive activation. The representation is compact and has a comparable structure as the classical neutron activation analysis (NAA) formulae, used in absence of burn-up and activation of daughter products. It is shown how singularities are avoided if different products have equal disappearance and/or decay rates. Explicit expressions are given for typical situations encountered in neutron activation analysis. Its incorporation into the k(0)-standardization is demonstrated for several decay types.
