DEF

A nuclide, stable or radioactive, formed by radioactive decay of another nuclide, which in this context is called the parent.

CONT

decay chain: A succession of radionuclides, each one formed by the decay of the previous one. In a radioactive decay chain the decaying nuclide is termed the "mother" radionuclide and the nuclide it decays to is termed the "daughter" nuclide.

CONT

Holmes & Holmes ... give a simple summary of the theory of how ages are deduced from the radioactive decay of an unstable parent isotope to a more stable isotope of a different element (daughter) ... the parent-daughter relationships ... are of major interest for dating rocks and ores.

OBS

"Nuclide" is here an elliptic term. Strictly speaking, it is not a synonym for "radionuclide," which is a specific: a radioactive nuclide.

OBS

daughter product: term standardized by ISO in 1997.

DEF

[Tout] nucléide qui suit un radionucléide spécifié dans une chaîne de désintégration. [Définition normalisée par l'ISO.]

CONT

On appelle produits de filiation les différents produits des désintégrations successives à partir du nucléide radioactif initial, appelé «père»; tous ces produits forment une «famille radioactive».

OBS

Le terme «nucléide» possède un sens plus large que «radionucléide» qui ne se rapporte qu'aux nucléides radioactifs. Il est ici employé comme synonyme elliptique, acceptable lorsque le contexte est suffisamment clair.

OBS

descendant; descendant radioactif : termes normalisés par l'ISO en 1997.
