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 produces gamma radiation, which is a type of electromagnetic radiation that is highly penetrating and can be used for various applications such as radiation therapy in cancer treatment and industrial radiography.
Cobalt 60 is a very valuable radiation source for the treaments of many types of cancers.
It is sometimes called radiation therapy, x-ray therapy radiation treatment, radiotherapy, electron beam therapy, or irradiation
The only natural isotope of Cobalt is Cobalt-59.
The half-life of cobalt-60 (Co-60) is approximately 5.27 years. This means that after this period, half of the original amount of Co-60 will have decayed into stable nickel-60. Co-60 is commonly used in radiation therapy and industrial applications due to its gamma radiation.
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.
When cobalt-60 emits a gamma ray, it remains as cobalt-60. The emission of a gamma ray does not change the identity of the cobalt-60 isotope.
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.
