【 摘 要 】

This paper presents a revision of the history, definitions, and classification of tracers (natural and artificial, internal and external). The fundamental ideas concerning tracers are described, followed by their application illustrated by typical examples. The advantages and disadvantages of five classes among the most frequently used external tracers (fluorescent, microbial, chemical, radioactive and activable isotopes) are also described in detail. This review also presents some interesting and modern applications of tracers in the areas of diagnostics in medical practice, environmental pollution, hydrology and petroleum chemistry.
