Abstract

Radiochemical conversion is an important term to be included in the "Consensus nomenclature rules for radiopharmaceutical chemistry". Radiochemical conversion should be used to define reaction efficiency by measuring the transformation of components in a crude reaction mixture at a given time, whereas radiochemical yield is better suited to define the efficiency of an entire reaction process including, for example, separation, isolation, filtration, and formulation.

Keywords: Consensus guidelines; Nomenclature; Nuclear chemistry; Radiochemical conversion; Radiochemical yield; Radiochemistry; Radiopharmaceutical sciences; Terminology.
