Amersham International introduced the Amertec™ technetium 99 generator replacing earlier models. The generator is vital in nuclear medicine departments throughout the world as the source of precise amounts of radioactivity, required as the active component of diagnostic agents such as Ceretec™, used in the diagnosis of brain disease. Pictured awaiting despatch, are rows of the upgraded Amertec II™ generator which won a 1987 Queen's Award and is still in use today.
