Production of Sc medical radioisotopes with proton and deuteron beams
Résumé
Proton and deuteron beams extracted from the PETtrace medical cyclotron
at the Radiopharmaceuticals Production and Research Centre in the University of
Warsaw, Heavy Ion Laboratory, 28 MeV protons from the C30 cyclotron at the
National Centre for Nuclear Research, Świerk, near Warsaw and 33 MeV protons
from the Arronax accelerator, Nantes were used to produce and investigate the
medically interesting Sc radioisotopes. Both natural and isotopically enriched
CaCO3 targets and highly enriched 48TiO2 targets were used. The production
efficiency and isotopic purity were determined and are reported here for the
highest commercially available enrichments of the target material. The Thick
Target Yield, Activities at the End of Bombardment (EOB) and the relative
activities of produced impurities at EOB are reported for 43Sc, 44gSc, 44mSc and
47Sc produced with particle energies below 30 MeV.
