In search of an alternative production route of the therapeutically and environmentally interesting radionuclide 191Pt (T1/2=2.8 d), excitation function of the 192Os(3He,4n)191Pt reaction was measured from its threshold up to 36 MeV. Thin samples of enriched 192Os were prepared by electrodeposition on Ni-foils, and the conventional stacked-foil technique was used for cross-section measurements. The experimental data were compared with the results of theoretical calculations using the codes ALICE-IPPE and TALYS. Good agreement was found with TALYS. The theoretical thick target yield of 191Pt over the energy range E3He=36→25MeV amounts to 6.7 MBq/μA h. A comparison of various investigated production methods of 191Pt is given. The here investigated 192Os(3He,4n)-process leads to very high-purity 191Pt (>99.5%).
