The IAEA’s aim is to help build Member States’ capacities to support them in establishing high-quality health care worldwide. Since the IAEA began its work in human health over 50 years ago, the use of nuclear techniques in medicine and nutrition has become one of the most widespread peaceful applications of atomic energy.The IAEA assists Member States with the coordination of research projects, expert guidance, equipment, the development of internationally harmonized guidelines, training and knowledge exchange. Its support ranges from nutrition interventions to cancer diagnosis and treatment, to quality assurance for the use of radiation in medicine for safe and accurate treatment of conditions such as cancer.
