What Is Cobalt Medicine?
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient’s body to kill tumor tissue.
What was cobalt medicine used for?
What is it used for? 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.
What is cobalt medical term?
Cobalt is a hard, gray metal element. It’s part of vitamin B-12. This vitamin is essential for making red blood cells (erythropoiesis). It also maintains the nervous system. Cobalt is in the body only as part of vitamin B-12.
Does cobalt have any health benefits?
Cobalt forms part of the structure of vitamin B12. Vitamin B12 has several important functions including making red blood cells and releasing energy from the food you eat.
What foods are high in cobalt?
Some of the dietary sources that are abundant in cobalt include red meat, milk, fish, cabbage, figs and turnips.
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 used in drugs?
Cobalt is a versatile transition metal for drug development. The tunable physicochemical properties can be exploited by understanding the mechanism of bioactive cobalt complexes.
Is cobalt vitamin B12?
Cobalt is a core element of vitamin B12 (cyanocobalamin), which is essential for the prevention of anemia in humans1.
What does cobalt poisoning do in the body?
Systemic toxic effects from excessive levels of cobalt include peripheral neuropathy, sensorineural hearing loss, vision loss, cognitive decline, cardiomyopathy, hypothyroidism, weakness, fatigue and polycythemia.
What diseases can cobalt cause?
* Cobalt may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. * Cobalt may affect the heart, thyroid, liver and kidneys. * Repeated exposure to Cobalt dust can cause scarring of the lungs (fibrosis) even if no symptoms are noticed.
What are 3 important uses of cobalt?
Cobalt is also used to make airbags in automobiles; catalysts for the petroleum and chemical industries; cemented carbides (also called hardmetals) and diamond tools; corrosion- and wear-resistant alloys; drying agents for paints, varnishes, and inks; dyes and pigments; ground coats for porcelain enamels; high-speed
What are the signs of cobalt poisoning?
If you have a metal-on-metal hip implant, is it vital to watch out for these signs of potential cobalt poisoning:
- Pain and irritation in the implant area.
- Swelling and inflammation.
- Severe discomfort and pain.
- Burning sensation.
- Weakness in the hip and joints.
- Pseudotumor growth.
- Numbness.
- Blood circulation issues.
How long does cobalt stay in the body?
Elevated blood levels of cobalt and chromium ions can persist for at least 1 year after revision, especially in patients with high levels of exposure.
How does the body get rid of cobalt?
Normal chromium levels range from 0.06 to 0.93 in healthy patients and the highest safe level in the bloodstream is considered to be 17 micrograms per liter of blood. Cobalt is not an accumulating metal, meaning it is stored in the liver and processed out of the body through urine but not stored in the bones.
Are tomatoes high in cobalt?
Total Co accumulation in tomatoes was as high as 873 μg g−1 in roots, 124 μg g−1 in stems, 167 μg g−1 in leaves and 21 μg g−1 in fruit–flowers. Cobalt was detected in all parts of the tomatoes, though not in fruit–flowers at lower treatment conditions.
Where can cobalt be found in the body?
The organic form of cobalt is present in green parts of plants, fish, cereals, and water [8, 9]. In the human body this element is present in amounts from 1 to 2 mg: we can find it in the heart, liver, kidney, and spleen, and considerably smaller quantities in the pancreas, brain, and serum [10, 11].
What cancers does cobalt-60 Treat?
Beam Energies
Cobalt 60 (60Co) is often the ideal mode of radiation for treating laryngeal cancer. For primary treatment of laryngeal cancer, 60Co allows adequate dosing of the superficial tissues.
When was cobalt-60 first used in medicine?
October 27, 1951
On October 27, 1951, the world’s first cancer treatment with Cobalt-60 radiation took place at Victoria Hospital. This marked an important milestone for both the fight against cancer and Canada’s emergence as a leader in the field of radiotherapy.
What are the benefits of using cobalt-60?
The advantages of Co/sup 60/ therapy over conventional x-ray therapy, stemming from the fact that in the lst instance energy absorption within the tissues is by the Compton effect and in the 2nd case by the photoelectric effect, are: (1) increased skin tolerance, (2) reduced bone absorption, (3) increase in depth dose,
What medical devices contain cobalt?
Cobalt (Co) alloys have been used for over seven decades in a wide range of medical devices, including, but not limited to, hip and knee implants, surgical tools, and vascular stents, due to their favorable biocompatibility, durability, and mechanical properties.
Do B12 injections have cobalt?
Cobalt is one of the components of vitamin B12, also known as cobalamin.
