This publication was produced under an IAEA coordinated research project and details the results of the work completed by the project counterparts in developing radiometric and complementary techniques for veterinary drug residues. The information is useful for research on, and technology transfer to facilitate, veterinary drug and associated residue testing in food and environmental samples. The publication presents a source of standard operating procedures that can be used for step-by-step laboratory analyses and will be useful for Member States in implementing food safety control programmes.
