Is cobalt-60 a beta particle emitter?
The most common radioisotope of cobalt is cobalt-60, which is a beta and gamma emitter.
What is cobalt-60 commonly 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 source of cobalt-60?
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 alpha beta or gamma?

Why is Cobalt-60 no longer used?
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 problem does Cobalt-60 solve?
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 beta particles of Cobalt 60?
Cobalt-60 (Co-60) Beta particles: electrons ejected from the nucleus of a decaying atom. Although they can be stopped by a thin sheet of aluminum, beta particles can penetrate the dead skin layer, potentially causing burns.
What kind of radiation can Cobalt 60 be used for?
Cobalt Sources. Cobalt-60 is used as a radiation source in many common industrial applications, such as in leveling devices and thickness gauges. It is also used for radiation therapy in hospitals.
Which is the most common radioisotope of cobalt?
The most common radioisotope of cobalt is cobalt-60, which is a beta and gamma emitter. Metallic cobalt-60 is commonly used in sealed gamma sources. Particles of cobalt dust adhering to small articles are readily removed by ultrasonic cleaners or by dipping the article in a dilute solution of nitric, hydrochloric, or sulfuric acid.
How is Cobalt 60 formed in nuclear reactors?
Cobalt-60 is a byproduct of nuclear reactor operations. It is formed when metal structures, such as steel rods, are exposed to neutron radiation. Beta Particles Beta Particle A form of particulate ionizing radiation made up of small, fast-moving particles.
