[en] The article reviews the historical development of the nuclear medicine in Colombia and the primordial role of the IAN in this field. The main objective of the Biochemistry and Radiopharmacy Area is go to give technical support for the application of the nuclear energy in the human and veterinary medicine. The department has laboratories for the production of radiopharmaceuticals to be labelled with Tc-99m and quality control of the same human and veterinary RIA. Each one of the laboratories develops its work in three different areas: research and development, production, training and teaching. An actualization of the programs, results and publications are analyzed in this review also. Some of these programs have the support of the IAEA
