Where detected

Cobalt-60 is produced artificially by subjecting the only stable isotope cobalt-59 to neutron bombardment (in a nuclear reactor or using a neutron generator). It is found as a reference source from old radiometers, flaw detectors, gamma therapy apparatuses, or as a marker of man-made accidents and nuclear tests. Due to its high-energy gamma radiation, it is difficult to shield.
