Pharmaceutical preparations containing radioactive elements have assumed increasing significance in the diagnosis and treatment of disease as well as in pharmacological studies attempting to establish the mechanisms of drug action. It is not surprising that the medical literature has also been enriched by constantly increasing numbers of reports on the use of these products. Unfortunately, the various styles of nomenclature used to describe these products in the earlier reports appeared to hinder dissemination of this information.
