The radioactive isotopes Be/sup 10/, Al/sup 26/, Cl/sup 36/, K/sup 4/ / sup 0/, and Mn/sup 53/ were measured in four iron meteorites: Grant, Williamstown, Odessa, and Canyon Diablo. Each sample was recycled to constant activity, using a different chemistry for each recycle wherever possible. The samples were counted with a low-level beta -counter, except for Mn/sup 53/ whose x-rays were measured. The isotope ratios were approximately constant for each meteorite, except for Mn/sup 53/ where a depth effect is visible. The cosmic-ray ages of Williamstown and Grant are about the same. (auth)
