摘要：

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: 47Ca/47Sc; 95Zr/95Nb; 140Ba/140La; 99Mo/99mTc and 115Cd/115mIn 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: 47Ti(n,p)47Sc/46Ca(n,γ)47Ca(β−)47Sc are evaluated with respect to the determination of the elements involved and their reciprocal interferences.
