Abstract

In this paper, radionuclidic impurities generated during the bombardment of a 20Ne gaseous matrix in the routine production of [18F]-Fluorodopa were studied. The 18F2 is produced by the GE PETtrace cyclotron capable of accelerating negative deuterons ions to an energy of 8.4 MeV. The materials of the target and of the Havar Foil, the stable Fluorine added as carrier and the natural isotope composition of Neon may interact with deuterons and produce undesired radionuclides. To measure them a sampling system has been realized. Samples of the irradiated gas have been measured by gamma-ray spectrometry. The results show how the radionuclidic purity obtained is very high after a short time from the end of bombardment (EOB).
