Is There A Shortage Of Cobalt-60?
Is there a Cobalt-60 shortage? Cobalt-60 supply has been under pressure in recent years, mostly due to some unexpected perturbations in the global supply chain. In addition, higher than historical growth in medical device manufacturing volume has meant that demand for Cobalt is out-pacing supply.
Is cobalt-60 still used?
Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.
Where is cobalt-60 produced?
nuclear reactors
WHERE DOES COBALT-60 COME FROM AND WHERE IS IT FOUND? Cobalt-60 is artificially produced by bombarding a target material, either cobalt-59 or nickel-60, with neutrons. This reaction is produced by nuclear weapons detonations and in nuclear reactors.
Is cobalt-60 used in nuclear power plants?
Cobalt-60 is a neutron activation product formed from structural materials in nuclear reactors. It can also be produced industrially through neutron activation of stable cobalt. It is used in nuclear medicine. Radiocobalts (the radioactive isotopes of cobalt) are found in nuclear power reactors.
What does the 60 stand for in cobalt-60?
: a heavy radioactive isotope of cobalt having the mass number 60 produced in nuclear reactors and used as a source of gamma rays especially in place of radium (as in the treatment of cancer and in radiography)
What happens if you pick up cobalt-60?
Because cobalt-60 releases gamma rays, it can affect the health of people nearby, even if they do not ingest or inhale it. Exposure to low levels of gamma radiation over an extended period of time can cause cancer.

Who has the biggest supply of cobalt?
The Democratic Republic of the Congo
The Democratic Republic of the Congo has the largest cobalt reserves in the world, at some 3.5 million metric tons as of 2021. As the total global cobalt reserves amount to 7.6 million metric tons, this means that the DR Congo’s cobalt reserves account for nearly half of the world’s reserves of the metal.
Who is the largest cobalt producer in the world?
The Democratic Republic of Congo (DRC)
The Democratic Republic of Congo (DRC) is by far the world’s largest producer of cobalt, accounting for roughly 70 percent of global production. The country has been the top producer of the metal for some time, and its output increased from 98,000 MT in 2020 to 120,000 MT in 2021.
Who is the largest exporter of cobalt?
The mining industry in the Democratic Republic of Congo is the most lucrative and essential part of the DRC economy. It is their largest source of export income. The DRC accounted for more than two thirds of global cobalt production in 2021, making it the world’s largest cobalt producer by a large margin.
Is cobalt-60 harmful to the environment?
Although cobalt is an essential trace element, it is toxic when concentration levels are too high. Protection criteria based on cobalt ecotoxicity data have been defined for the terrestrial and aquatic ecosystems. Its radiotoxicity is also known for these environments. Cobalt is a grey, lustrous, ferromagnetic metal.
What is the most radioactive thing on earth?
radium
The radioactivity of radium then must be enormous. This substance is the most radioactive natural element, a million times more so than uranium.
What’s the most radioactive element?
Polonium. Because it is a naturally-occurring element that releases a huge amount of energy, many sources cite polonium as the most radioactive element.
Is cobalt-60 natural or man made?
Cobalt-60 is not found in nature. It is a synthetic radioactive isotope made by neutron activation of Cobalt-59. Cobalt-60 is produced off site in nuclear reactors and transported in special shipping containers (casks) to the sterilization facility.
Why is cobalt-60 unstable?
One of its synthetic isotopes, Cobalt-60 (Co-60), has an extra neutron in its nucleus that makes it unstable. As it breaks down, Co-60 emits high energy, “ionizing” radiation that can break molecular bonds.
How abundant is cobalt-60?
Cobalt-60
| General | |
|---|---|
| Natural abundance | trace |
| Half-life (t1/2) | 5.27 years |
| Isotope mass | 59.9338222 Da |
| Spin | 5+ |
How much of cobalt-60 is lethal?
At a dose of 100 rem, a person will start to feel ill. By the time they’ve received 800 or so rem, they will likely die from the exposure.
Does cobalt replenish?
Cobalt-60 decays continuously. The time taken to lose 50% of its initial activity, i.e., its half-life, is 5.26 years. Usually 10% of the cobalt-60 is replenished annually.
Can cobalt be destroyed?
❏ Cobalt cannot be destroyed. It can change form or attach to or separate from particles. Radioactive decay is a way of decreasing the amount of radioactive cobalt in the environment.
Why is cobalt so valuable?
Current battery technologies require cobalt as part of the cathode. Given the growing popularity of electric vehicles, demand for cobalt continues to increase. Near-term trends suggest demand will outstrip supply, thus increased prices.
Is there a market for cobalt?
While there has always been a market for recycling cobalt, now that we’re seeing high prices again there is an even greater need and want for it.
