Production of short-lived PET-radionuclides has a history in Turku extending to the middle 1970s. The MGC-20 cyclotron was installed in 1974 and the production of short-lived radionuclides started soon after. 11C-, 13N-, 15O- and 18F-precursors have been produced for various applications. The MGC-20 cyclotron has also been used for the production of longer-lived radionuclides especially in connection with nuclear reaction cross-section measurements.
At present our capabilities are based on the utilization of our four cyclotrons, three of which are located in the Turku University Hospital PET-building.
The CC-18/9 cyclotron (K=18, proton and deuteron beams, proton-beam current of 100 microamperes) taken in operation in 2006 is used for production of 18F, 11C and 64Cu isotopes, needed in research and as pre-cursors for radiochemical syntheses. Most of the targetry related research is presently conducted on the CC18/9 cyclotron.
The ACSI TR-19 cyclotron (K=19, variable energy, proton beam, beam current 2 x 120 microamperes) taken in operation in 2015, is used for production of 18F, 11C and 82Br isotopes, needed as pre-cursors for radiochemical syntheses and for research purposes.
The IBA 3D cyclotron (K=3.5, deuteron beam, beam current 50 microamperes taken in operation in 1992) is solely dedicated for production of 15O in gas form and as radio-water.
Our first cyclotron, the MGC-20 (K=20, multiparticle, variable energy, proton-beam current of 10 microamperes) installed in the Gadolinia building of Åbo Akademi University in 1974, is also still in routine operation, producing 18F and 11C isotopes for pre-clinical research. Additionally the MGC-20 cyclotron is also used for trace-element analyses utilizing the PIXE-technique (Particle Induced X-ray Emission).
