    Aim Alpha emitting radiometals are promising tools for cancer treatment. One of them is 223Ra (half-life of 11.4 days) together with its mother nuclide, 227Th (half-life of 18.7 days).These nuclides can be obtained from 227Ac/227Th/223Ra generator produced via 226Ra(n,γ)227Ra/227Ac reaction using nuclear reactor. This fact puts, however, high requirements on radiation stability of such a generator. Aim of this study was to develop alternative method for direct cyclotron production of 227Th via 226Ra(α,3n) reaction. Methods Cross-sections of the 226Ra(α,3n) reaction were adopted from TENDL-2012 library based on TALYS nuclear model code. Using these data, thick target yields of this reaction were calculated. Experimental verification of the predicted values was performed on a U-120M isochronous cyclotron of the Nuclear Physics Institute of the Academy of Science of the Czech Republic by irradiating single thin 226Ra targets.
