How Is Cobalt 57 Used In Medicine?
Uses. Cobalt-57 isused in medicine to help detect cancerous tumors. It is also used as a component in the medical equipments studying the chemical properties of various materials or testing the response of Gamma cameras.
Where is the Cobalt-57 used?
Use of cobalt radioisotopes in medicine
Cobalt-57 (57Co or Co-57) is used in medical tests; it is used as a radiolabel for vitamin B12 uptake. It is useful for the Schilling test. Cobalt-60 (60Co or Co-60) is used in radiotherapy. It produces two gamma rays with energies of 1.17 MeV and 1.33 MeV.
What type of radiation does cobalt-57 emit?
γ-rays
1 PHYSICAL AND CHEMICAL PROPERTIES
The main radioactive isotopes 57Co, 58Co, and 60Co decay with respective half-lives of 272 days, 71 days, and 5.271 years, and emit γ-rays.
What is Cobalt-57 half-life?
Cobalt-57 decays with a half-life of 270 days by electron capture and
Is cobalt radio active?
Cobalt (chemical symbol Co) is a hard, gray-blue metal that is solid under normal conditions. Cobalt is similar to iron and nickel in its properties and can be magnetized like iron. The most common radioactive isotope.
What is Cobalts main use?
Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical. On a global basis, the leading use of cobalt is in rechargeable battery electrodes.
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.
What is the deadliest radioactive material?
Polonium
Polonium is a highly radioactive heavy metal. It is arguably the most lethal known material. Although it has some minor industrial uses it is best known for links with possible assassinations. It is also used to produce neutrons in the core of nuclear weapons.
What is the strongest radioactive metal?
The correct answer is Polonium. Polonium is a radioactive chemical element atomic number 84 that was discovered in 1898 by Marie Curie, who named the element after her country, Poland. In its natural state, at room temperature, polonium is solid metal with a silver color.
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 treatment still used?
Because these “cobalt machines” were expensive and required specialist support, they were often housed in cobalt units. Cobalt therapy was a revolutionary advance in radiotherapy in the post-World War II period but is now being replaced by other technologies such as linear accelerators.

Is cobalt toxic to humans?
It can harm the eyes, skin, heart, and lungs. Exposure to cobalt may cause cancer. Workers may be harmed from exposure to cobalt and cobalt-containing products. The level of harm depends upon the dose, duration, and work being done.
How much cobalt is lethal?
* Exposure to 20 mg/m3 is immediately dangerous to life and health.
What replaced cobalt?
Chevrolet Cruze
Replacement. In 2009, Chevrolet launched the Cobalt’s eventual successor, the Chevrolet Cruze (based on the new Delta II platform), in Europe, with launches in other markets (including the US) following in 2010. The Cobalt ended production on June 23, 2010.
Where is cobalt found in real life?
Cobalt is found in the minerals cobaltite, skutterudite and erythrite. Important ore deposits are found in DR Congo, Canada, Australia, Zambia and Brazil. Most cobalt is formed as a by-product of nickel refining.
What devices contain cobalt?
Today it is a metal found in many products ranging from aircraft engines to lithium-ion batteries, including those in electric vehicles. Currently, the largest use of cobalt is in portable consumer electronics like cell phones, laptop computers, and tablets, which are all powered by lithium-ion batteries.
Why is cobalt important today?
Cobalt has been used for a long time across different industries and products like superalloys, magnets, electronics, and even paint. But the so-called lithium-ion batteries now account for more than 50% of the demand for cobalt today.
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.
What are 3 interesting facts about cobalt?
Five astonishing facts about cobalt
- Cobalt is named after mythical, death-dealing goblins.
- We’ve used cobalt dye for at least 2,600 years.
- Cobalt can treat cancer…but also kill you.
- Cobalt used to be a beer additive – with disastrous effects.
- Cobalt is key to cutting edge technology and a greener future.
How many years of cobalt do we have left?
More than 70% of the world’s cobalt is produced in the Democratic Republic of Congo, and any nation that produces electronics wants in on that source. But based on operational mines and projected demand, forecasters predict that supply won’t be able to keep up with demand by 2030, or even as early as 2025.
What country produces 70% of the world’s cobalt?
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.
