Radiochemical methods in production of radionuclides at a cyclotron

Extensive use of radiochemical methods has been made over decades in radionuclide development work at different cyclotrons at the Forschungszentrum Jülich. In this article, a brief overview of the methods used in investigations on nuclear data, high-current targetry, chemical processing, etc. is given, with some typical examples in each area. The large and clinical scale productions of some standard and non-standard positron emitters, respectively, using the proton and deuteron beams at a small cyclotron are elaborated. Furthermore, some ongoing development work on two therapeutic radionuclides of great current interest, namely 193mPt and 211At, using the α-particle beam at the new medium-sized cyclotron, is described.
