| مستخلص: | The radiotherapeutic 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 195m Pt through double neuron capture of enriched 193 Ir followed by β - -decay to the radioisotope of interest carried out at the research reactor IBR-2 is described. Because of the high radiation background, radiochemical purification procedure of 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 194 Ir(n,γ) 195m Ir were determined. Resonance neutrons contribution was established to exceed that of thermal neutrons, and resonance integral for the reaction 194 Ir(n,γ) 195m Ir is calculated to be 2900 b. Specific activity of 195m Pt was estimated to reach a value of 38.7 GBq/(g Pt) at IBR-2 by the end of bombardment (EOB).
