An unstable nucleus spontaneously releases a positron. This is an example of radiation.
Further Explanation:
Radiations are the emission of energy in the structure of waves. There is a different type of radiations such as:
Radioactive decay is a reaction by which an unstable nucleus of an atom loses energy by releasing radiation and converts into a stable nucleus. Three types of particle are:
Examples of positrons are alpha and beta particles. Alpha decay is a nuclear process in which alpha particles are released. In beta decay, a beta particle is released from the nucleus.
Beta-decay is two types:
In β- decay, the nucleus has a high level of the neutrons which then converted into electron neutrino, electron, and proton. In β+ decay, the nucleus has a high level of protons which then converted into a positron, electron neutrino, and neutron. β-particle is a very high ionizing particle which is hazardous to living tissue.
