The radiotherapeutic &sup(195m)Pt is among the most effective Auger electron emitters of the currently studied radionuclides that have a potential theranostic application in nuclear medicine. Production of &sup(195m)Pt through double neuron capture of enriched *1*9*3Ir followed by *b -decay to the radioisotope of interest carried out at the research reactor IBR-2 is described. Because of the high radiation background, radiochemical purification pro- cedure of &sup(195m)Pt from bulk of iridium was needed to be developed and is detailed here as well. For the first time, cross section and resonance integral for the reaction *1*9*4Ir(n,*g)&sup(195m)Ir were determined. Resonance neutrons contribution was established to exceed that of thermal neutrons, and resonance integral for the reaction *1*9*4Ir (n,g)&sup(195m)Ir is calculated to be 2900 b. Specific activity of &sup(195m)Pt was estimated to reach a value of 38.7 GBq/(g Pt) at IBR-2 by the end of bombardment (EOB).
