Elementary principles of the tracer method -- Tracer experiments in compartmental systems -- Theory of tracer experiments in multi-compartment systems -- Kinetic equations for compartmental systems -- Other steady-state and quasi-steady systems, approximation methods -- Analog simulation of compartmental tracer experiments -- Non-steady-state compartmental systems -- Non-compartmental systems - basic tracer equations -- Tracers and teh study of the circulation -- Movement of tracer substances from the circulation -- Matrix methods and fitting models to data. It is the purpose of this book to collate and unify the literature on the Tracer Method. Perhaps, as a result, some existing barriers between fields will be overcome with improved communication between workers. It is also hoped that a broader appreciation of the nature of the tracer method and a clearer understanding of its present scope and limitations will be created.
