What is the use of CO-60 isotope?
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.

How is cobalt60 made?
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 HAZARDOUS? Cobalt-60 emits two high energy gamma rays, making cobalt-60 both an internal and external hazard.
Why is cobalt-60 used in medicine?
Cobalt-60 is used in the inspection of materials to reveal internal structure, flaws, or foreign objects and in the sterilization of food. In medicine, it is used to treat cancer and to sterilize medical equipment.
What are the side effects of cobalt radiation?
They could have diarrhea, a headache, and a fever. They may be vomiting—perhaps even vomiting blood. Their stomachs and intestines could be bleeding. The radiation has probably depleted their supply of red and white blood cells.
Is cobalt used in medicine?
Cobalt-60 is widely used as a medical and industrial source of radiation. Medical use consists primarily of cancer radiotherapy.
What is a cobalt-60 machine?
The machine is intended to deliver precise radiation treatment to the patient suffering from a cancerous growth. Cobalt-60 therapy can be used anywhere on the body but is particularly useful in brain tumour patients because of its preciseness. There are two types of sources that are used for radiation therapy.
How long does cobalt-60 stay in the body?
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.
Is NB 92 radioactive?
Naturally occurring niobium (41Nb) is composed of one stable isotope (93Nb). The most stable radioisotope is 92Nb with a half-life of 34.7 million years. Most of these have half-lives that are less than two hours, except 95Nb (35 days), 96Nb (23.4 hours) and 90Nb (14.6 hours).
Is cobalt therapy still used?
Cobalt treatment still has a useful role to play in certain applications and is still in widespread use worldwide, since the machinery is relatively reliable and simple to maintain compared to the modern linear accelerator.
How is cobalt-60 used in radiotherapy?
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 is co 60 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. Co-60 also is used for food irradiation, a sterilization process.
What is the half life of co 60?
The half life of Cobalt-60 is about 166,239,000.00 seconds
What is half life of co 60?
Co-60 has a biological half life of 9.5f days, and an effective half life of 9.5 days. The maximum permissible body burden (MPBB) is 1.0 uCi, based on Stanford Guideline of whole body dose not exceeding 500 mRem/yr.
What is Cobalt 60 source?
Sources can be shipped in the source projector or in a suitable returnable transport container. COBALT-60 Cobalt-60 sources are constructed using compression fused cobalt metal pellets confined within welded titanium and stainless steel capsules.
