Types of Nuclear Radiations
Topic Content:
- Types of Nuclear Radiations
As a result of the difference in stability of different nuclei, there are four types of nuclear reactions.
1. Radioactive decay: This refers to the emission of an alpha particle (α), a beta particle (β), or gamma radiation (γ) and the formation of a slightly lighter and more stable nucleus.
2. Nuclear Disintegration: A nucleus is bombarded with alpha particles, particles, protons, deuterons (deuterium nuclei, \( \scriptsize _{1} ^{2} \textrm {H}\)), neutrons, or other particles. The unstable nucleus emits a proton or a neutron and becomes more stable in a process called nuclear disintegration.
3. Nuclear Fission: This refers to the process in which a very heavy nucleus splits to form medium-mass nuclei.
4. Nuclear Fusion: This is the process in which light mass nuclei combine to form heavier, more stable nuclei.
