Use of an isotopically distinguished form of an element to follow transport, exchange, reaction, or turnover without changing elemental identity.

This is an authored directed relation from the source endpoint to the target endpoint.
An isotope becomes a tracer when its distinguishable abundance or decay signature is introduced or observed to follow material through a chemical, biological, or environmental system.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

This is an authored directed relation from the source endpoint to the target endpoint.
An isotopically enriched tracer supplies the spike in isotope-dilution analysis; accurate inference requires known spike composition, equilibration, ratio measurement, blank correction, and a stated measurement equation.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
