Background. Tracer production for nuclear medicine. Objective. The aim of the paper is to consider the possibility of 99m Tc tracer production using low-energy medical cyclotrons installed in Ukraine applying enriched 100 Мо targets. Tc tracer yield equals 3.7 and 35.5 GBq after 2h of bombardment for Eclipse RD and PETtrace cyclotrons, respectively. Conclusions. The obtained results showed satisfied 99m Tс tracer yields and feasibility of further development of this method, which will significantly improve the efficiency of cyclotron installations.

In this work we present the new target assembly developed for solid samples irradiation by protons with different energies at maximum of 11 MeV and 40 μA for current. The new target was designed and manufactured for conventional target changer (carousel) of 11 MeV Eclipse RD medical cyclotron. The MCNP simulation of the beam profile after degradation was performed and testing irradiation of the target assembly was successfully carried out showing the target suitability for such type of cyclotron facilities.
