| cobalt | <chemical> A trace element that is a component of vitamin b12. It has the atomic symbol co, atomic number 27, and atomic weight 58.93. It is used in nuclear weapons, alloys, and pigments. Deficiency in animals leads to anaemia; its excess in humans can lead to erythrocytosis. Chemical name: Cobalt (12 Dec 1998) |

| cobalt isotopes | <radiobiology, physics> Stable cobalt atoms that have the same atomic number as the element cobalt, but differ in atomic weight. Co-59 is a stable cobalt isotope. (12 Dec 1998) |
| cobalt machine | <apparatus> A simple but effective source of irradiation which is employed for external beam radiotherapy. It has limited ability to focus irradiation. (16 Dec 1997) |
| cobalt radioisotopes | Unstable isotopes of cobalt that decay or disintegrate emitting radiation. Co atoms with atomic weights of 54-64, except 59, are radioactive cobalt isotopes. (12 Dec 1998) |
| cobalt-57 | <radiobiology> A radioisotope with a half-life of 271.8 days. It decays by electron capture with emission of a medium energy (122.06 keV) gamma ray. Used as a diagnostic aid with some metabolic disorders. (17 Jul 2002) |
| cobalt-58 | <radiobiology> Positron emitter with half-life of 70.88 days. (05 Mar 2000) |
| cobalt-60 | <radiobiology> A radioisotope with a half-life of 5.271 years. It emits beta particles and energetic gamma rays, for which reason it is used in radiation therapy and diagnostics in place of radium or X-rays. It is also used as a diagnostic aid in vitamin B12-related problems. (05 Mar 2000) |
| cobaltochelatase | <enzyme> Incorporates co(ii) into porphyrins Registry number: EC 4.99.1.- Synonym: co(ii)-chelatase (26 Jun 1999) |
| cobaltous chloride | CoCl2-6H20;used in the treatment of various types of refractory anaemia to improve the haematocrit, haemoglobin, and erythrocyte count. (05 Mar 2000) |
| chrome-cobalt alloys | Alloy's of cobalt and chromium containing molybdenum and/or tungsten plus trace elements; used in dentistry for denture bases and frameworks, and other structures. (05 Mar 2000) |
