Radiopharmaceutical Production for PET Imaging in Poland

tom 127

nr 5

1520-1522

At the beginning of 2000 the PET technique was not available in Poland. The structure and organization of the Radiopharmaceuticals Production and Research Centre at the Heavy Ion Laboratory, University of Warsaw is described as an example of a production department. The present status of several radiopharmaceutical production departments is presented which should give a comprehensive outlook of radiopharmaceutical production capabilities in Poland over the next few years.

The paper presents high-resolution X-ray diffraction studies performed for Si single crystal: as-grown, implanted with a 5×10^{14} ions· cm^{-2} dose of 3 MeV/n Ar ions, as well as implanted and annealed in a very high vacuum. The results are discussed on the basis of rocking curves and the mathematical analysis of the reciprocal space maps. It is shown that the lattice parameter is increased in an implanted part of the crystal, but long distance lattice curvature is not present. After annealing full relaxation of the crystal is stated.

The influence of heavy ion irradiation on the magnetic properties of the spin-Peierls compound CuGeO_{3} has been investigated by means of the electron paramagnetic resonance, the spontaneous magnetization, and the low field ac susceptibility. The measurements were performed on the CuGeO_{3} single crystals before and after irradiation with 80 MeV oxygen ions in the wide temperature range of 2-300 K. It was found that the irradiation induced an increase in the EPR signal intensity, magnetization, and susceptibility of this material. It was also shown that the irradiation does not lead to a decrease in the spin-Peierls transition temperature and to the formation of an antiferromagnetic phase which is expected to appear in disordered spin-Peierls systems.

The research of the surface and the near-surface region of Cz-Si wafers irradiated with fast oxygen and neon ions of energy 4 MeV/u and dose 10^{14} particles/cm^{2} is presented. In our study several methods based on the Bragg case of X-ray diffraction using Ag K_{α_{1}}, as well as reflection high-energy electron diffraction and Nomarsky optical microscopy were used. It was shown that implantation with fast neon ions causes larger disturbances of silicon crystal structure than irradiation with oxygen ions.

The internal alpha particle beam of the heavy ion cyclotron operated by the Heavy Ion Laboratory (HIL) of the University of Warsaw has a maximum energy of 32 MeV and currently an intensity of up to 1 pμA. This beam is used by the HIL-University of Silesia collaboration for the production of research quantities of ^{211}At, ^{72}Se/^{72}As and ^{43,44}Sc radioisotopes. The produced activities are transported to the Institute of Nuclear Chemistry and Technology in Warsaw where research on therapeutic and imaging radiopharmaceuticals based on these radioisotopes is pursued.
