The 40‐MeV direct beam bremsstrahlung irradiation facility of the Sagittaire clinical electron accelerator was used to produce 197 Ir via the reaction 198 Pt(γ, p ) 197 Ir. Gamma emitted in the Ir decay were detected with an intrinsic germanium system and multichannel analyzer. 106 of the spectrum peaks could be analyzed for energy, relative intensity, and half‐life. Half‐life results indicate that 197 Ir decays from two isomers, one with half‐life 6.1±0.1 min and another with half‐life 8.9±0.1 min.
