Minute quantities of this element may be found in uranium ores and are caused by spontaneous fission.
Minute quantities of this element may be found in uranium ores and are caused by spontaneous fission.* Its detection in the stellar spectra of red giants has bolstered the theory that stars produce heavy elements. One of its ions may find use in corrosion prevention in steel, though it is radioactive. It is used as a gamma ray-free source of beta rays and in nuclear medicine. FTP, name this element, the first to be artificially produced and which Mendeleev called ekamanganese.
