A metal element possessing radioactive isotopes used in the treatment of some cancers.
An essential mineral needed as a component of vitamin B12.
Cobalt is a mineral that forms part of the structure of vitamin B12 (also known as cobalamins). No other nutritional functions of cobalt have been clearly identified.
Metallic element, the radioactive isotope of which (Co-60) is used in the treatment of cancer. Cobalt is contained in vitamin B12.
A metallic element. The artificial radioisotope cobalt-60, or radiocobalt, is a powerful emitter of gamma radiation and is used in the radiation treatment of cancer. Cobalt itself forms part of the vitamin B12 molecule.
A gray, hard, ductile metallic chemical element; atomic weight 59.933, atomic number 27, specific gravity 8.9. Cobalt deficiency causes anemia in ruminants, but this has not been demonstrated in humans. Cobalt is an essential element in vitamin B12. Cobalt stimulates production of red blood cells, but its use as a therapeutic agent is not advised. In children, cobalt overdose may cause death. In adults, it may cause anorexia, nausea, vomiting, deafness, and thyroid hyperplasia with resultant compression of the trachea.
Cobalt is a metallic element present in various foods as an integral component of vitamin B12. Additionally, a radioactive variation of cobalt is employed in the field of radiotherapy.
