Medical Radioisotopes Produced with Cyclotron Beams in Warsaw

Abstract

The various production routes of the prospective medical radioisotopes 43Sc, 44gSc, 44mSc, 47Sc, 44Ti/44gSc, 99mTc, 72Se/72As and 211At were investigated by a team from the Heavy Ion Laboratory, University of Warsaw (HIL-UW), the University of Silesia (US) and the National Centre for Nuclear Research (NCNR). Three cyclotrons were employed: the K=160 heavy-ion cyclotron with an internal 32 MeV alpha particle beam and the p/d PETtrace medical cyclotron at HIL and the C30 proton cyclotron at NCNR in Świerk, near Warsaw. The Thick Target Yields, activity at the End of Bombardment (EOB) and the impurities produced in addition to the main isotope are reported. The possible medical applications of these radioisotopes are briefly discussed.
