Targets for Production of the Medical Radioisotopes with alpha and proton or deuteron Beams

摘要

The research quantities of some medical radioisotopes were produced in reactions induced by 32 MeV internal alpha beam (~(211)At, Sc isotopes), 16 MeV and 28 MeV proton beams (Sc isotopes) and 8 MeV deuteron beam (Sc isotopes). The frame-less targets used for irradiation with internal alpha beam were prepared from elemental (Bi for ~(211)At) and compound (CaCO_3 for Sc radioisotopes) materials. The CaCO_3 powder targets were also used for production of Sc radioisotopes with proton or deuteron external beams. Methods developed for preparation of the targets suitable for the irradiating beam type are described in this work.
