The nucleosynthesis of the radioactive nuclei Fe(59), Fe(60) and Co(60) under hydrostatic He-burning conditions is investigated in a parameterized way (i.e. at constant temperature and density) using a full and up-dated s-process network. It is found that significant quantities of those nuclei can be produced in realistic shell He-burning conditions met in massive stars. The implications of these results for galactic gamma-ray line astronomy of point and diffuse sources are evaluated semi-quantitatively. It is suggested that an 'average' galactic type II supernova would give detectable gamma-ray fluxes of the Fe(59) line, and that a diffuse Fe(60) emission line from the galactic plane should be observable with next generation instruments.
