The theoretical and practical aspects of the use of radioactive daughters originated from the decay of longer-lived radioactive mothers in parametric activation analysis, when the ratio: mother half-life to daughter half-life is less than 10, are discussed. The mother-daughter relationships: Ca/Sc; Zr/Nb; Ba/La; Mo/Tc and Cd/In are selected as models for the study. The cases when the radionuclide of interest is formed through both direct and indirect routes are also analyzed. As illustrative example, the direct reaction and the reaction chain: Ti(n,p)Sc/Ca(n,γ)Ca(β)Sc are evaluated with respect to the determination of the elements involved and their reciprocal interferences.

    Half-life number sequences collected from nuclear data charts are found to obey the Newcomb--Benford law. Based on this fact, it has been suggested recently, that this law should be used to test the quality of nuclear decay models. In this paper we briefly recall how, when and why the...
