In order to evaluate the risk of long-term storage of accelerator waist, the knowledge on the nuclide production by spallation reactions of the very long-lived isotopes is mandatory. One of these isotopes is 60Fe. However 60Fe is difficult to determine because of its half-live of T1/2=1.5My which deny the access by decay measurements. The method of choice is AMS. But there is the interfering stable isobare 60Ni which demands for elaborated techniques. Only a dedicated separation chemistry for Ni in conjunction with a powerful AMS facility can overcame theses obstacles. In this poster we will show the principles of this method with the results of the measurements.
