A succession of radioactive transformations linking a parent nuclide to daughter nuclides until a stable or effectively terminal state is reached, with branching, half-lives, and chemical separation history specified where relevant.

This is an authored directed relation from the source endpoint to the target endpoint.
A radioactive decay chain is composed of successive radioactive transformations between designated parent and daughter nuclides; branching and very long-lived intermediates must be included when they affect the stated chain model.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.
wp-physics-radioactive_decayiaea-livechartiupac-nuclideThis is an authored directed relation from the source endpoint to the target endpoint.
A radioactive decay chain is described by the identities, decay modes, branching fractions, and half-lives of its parent and daughter radionuclides, while chemical separation can change which members are retained in a sample.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

This is an authored directed relation from the source endpoint to the target endpoint.
For dating systems involving a chain member, parent–daughter production and secular-equilibrium relations can be required; other radiometric methods use a selected parent–daughter pair rather than the full chain.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
