What is Cobalt?

  • Cobalt is a naturally-occurring element that has properties similar to those of iron and nickel.
  • Small amounts of cobalt are naturally found in most rocks, soil, water, plants, and animals, typically in small amounts.
  • Cobalt is also found in meteorites.
  • The Elemental cobalt is a hard, silvery grey metal.

However, cobalt is usually found in the environment combined with other elements such as oxygen, sulphur, and arsenic. Cobalt can also exist in radioactive forms. Cobalt cannot be destroyed in the environment. It can only change its form or become attached or separated from particles

  • Once cobalt enters your body, it is distributed into all tissues, but mainly into the liver, kidney, and bones.
  • After cobalt is breathed in or eaten, some of it leaves the body quickly in the faeces.
  • The rest is absorbed into the blood and then into the tissues throughout the body.
  • The absorbed cobalt leaves the body slowly, mainly in the urine.

Health effects of Cobalt on humans.

  • Health effects such as cancer or birth defects.
  • Can experienced serious effects on the heart.
  • In some cases, these effects resulted in death.
  • Nausea and vomiting were usually reported before the effects on the heart were noticed.
  • Effects on the thyroid were found in people exposed to 0.5 mg cobalt/kg for a few weeks.
  • Vision problems were found in one man following treatment with 1.3 mg cobalt/kg for 6 weeks.
  • Being exposed to radioactive cobalt may be very dangerous to your health.
  • If you come near radioactive cobalt, cells in your body can become damaged from gamma rays that can penetrate your entire body, even if you do not touch the radioactive cobalt.
  • Radiation from radioactive cobalt can also damage cells in your body if you eat, drink, breathe, or touch anything that contains radioactive cobalt.
  • Your skin might blister or burn, and you may lose hair from the exposed areas.

 

This happens to cancer patients treated with large amounts of radiation to kill cancer.
Cells in your reproductive system could become damaged and cause temporary sterility.
Exposure to lower levels of radiation might cause nausea, and higher levels can cause vomiting, diarrhea, bleeding, coma, and even death.
