Cobalt-60 decays by beta particle emission to highly excited isomers of Nickel-60, as these isomers relax to the ground state of Nickel-60 highly energetic gamma rays are emitted.
The decay equation is:Co-60----------------------Ni-60 + e-
Beta Particle
radiation just means energy that travels. radio waves are just a type of radiation, so is visible light. anything that radiates, including heat, is radiation.
Radium emits alpha, beta, and gamma radiation. Alpha radiation is fully ionized helium nuclei. Beta radiation is high energy electrons. Gamma radiation is very high energy electromagnetic radiation. All of these can do significant damage to living things.
Gamma. And a whole lot of it.
gamma
Cobalt 60 is a very valuable radiation source for the treaments of many types of cancers.
Gamma radiation destroy harmful microorganisms and insects.

A cobalt-60 from Delhi University, which was unused for 25 years, was sold to unsuspecting scrap dealers. They then dismantled it and due to the harmful radiation emmited by the cobalt-60 pencils, there were 5 people who were exposed to radiation in which one died.
Cobalt 60 is not used in medicine as tracer. Cobalt 60 is used to destroy cancer tumors by gamma irradiation. Uranium has a gamma radiation with an energy of about 185 keV, very small to be used for a medicinal irradiation.
If cobalt-60 enters the human body some of it can be excreted in feces but the remainder of it is absorbed usually into the liver, kidney or bones and can cause cancer from prolonged exposure to gamma radiation.
Cobalt-60 usually emits beta radiation, though it is associated with a smaller amount of gamma radiation. If it is ingested in sufficient quantity it can contribute to radiation poisoning, and this can lead to cancer, tumors, and genetic damage.
Cobalt-60 is the radioisotope that acts as an external source of ionizing radiation in the treatment of cancer.
In modern times, Cobalt-60 is the substance used to make self-luminous paint. Cobalt-60 has replaced Radium's use for the same applications due to Radium's radiation danger.
Cobalt-60
Cobalt 60 is a blessing and a curse. An extremely small amount can be placed in a cancer and give it a lethal dose of radiation. If you are around a large amount or cobalt 60, you would be cooked. If you survived, you would slowly develop leukemia as you lost the ability to create stem cells.
