What is Cobalt 60 used for?
However, one of the best-known CO-60 uses is radiation therapy. When doctors administer it in carefully controlled conditions, it targets cancerous cells while causing minimal damage to surrounding tissues. As such, cobalt is a highly versatile substance with many different applications.
What is cobalt and why is it important?
Cobalt is a hard, silver-gray metal that occurs naturally in rocks, soil, water, plants, and animals. It is a trace mineral, meaning that we require tiny amounts to maintain good health. There is just 1–2mg of cobalt in the body, but it plays an essential role. It is a crucial component of vitamin B12, also known as cobalamin.

Radiotherapy can be delivered with a cobalt-60 unit or a linear accelerator (linac). In early stage breast cancer, radiotherapy is an integral part of breast-conserving treatment.
What are the side effects of cobalt radiation?
Because it decays by gamma radiation, external exposure to large sources of Co-60 can cause skin burns, acute radiation sickness, or death. Most Co-60 that is ingested is excreted in the feces; however, a small amount is absorbed by the liver, kidneys, and bones.
What types of cancer does cobalt-60 Treat?
For many brain cancers, Cobalt-60 therapy is one of the most precise and advanced forms of radiation treatment available. Gamma Knife radiosurgery is a type of radiation therapy used to treat tumours and other abnormalities in the brain.

Cobalt and Health Because it decays by gamma radiation, external exposure to Co-60 can increase cancer risk. Most Co-60 that is ingested is excreted in feces; however, a small amount is absorbed by the liver, kidneys and bones.
What type breast cancer has the highest recurrence rate?
Research suggests that estrogen receptor-positive breast cancer is more likely to come back more than five years after diagnosis. In this study, the researchers looked at the risk of late breast cancer recurrence, meaning the breast cancer came back 10 or more years after diagnosis.
Do tumors grow back after radiation?
Normal cells close to the cancer can also become damaged by radiation, but most recover and go back to working normally. If radiotherapy doesn't kill all of the cancer cells, they will regrow at some point in the future.

Is radiotherapy worse than chemo?
Radiation therapy involves giving high doses of radiation beams directly into a tumor. The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

The first patient to be treated with cobalt-60 radiation was treated on October 27, 1951, at the War Memorial Children's Hospital in London, Ontario. In 1961 cobalt therapy was expected to replace X-ray radiotherapy. In 1966, Walt Disney 's lung cancer was treated with this procedure, but could not prevent his death.
What is the activity of Cobalt-60?

Why were cobalt machines used in radiotherapy?
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.
How much energy does cobalt 60 have?
As used in radiotherapy, cobalt units produce stable, dichromatic beams of 1.17 and 1.33 MeV, resulting in an average beam energy of 1.25 MeV. The cobalt-60 isotope has a half-life of 5.3 years so the cobalt-60 needs to be replaced occasionally.
Where was the Cobalt 60 made?
Two cobalt-60 apparatuses were then built, one in Saskatoon in the cancer wing of the University of Saskatchewan and the other in London, Ontario. Dr. Johns collected depth-dose data at the University of Saskatchewan which would later become the world standard.
