ALPHA PARTICLE Meaning and
Definition
-
An alpha particle refers to a type of nuclear radiation consisting of two protons and two neutrons, giving it a positive charge equivalent to the charge of a helium nucleus. It is a byproduct of radioactive decay and is usually emitted during the process of alpha decay, in which a radioactive atom releases an alpha particle in order to stabilize itself. In terms of physical appearance, an alpha particle is typically described as a very fast-moving, highly energetic particle.
Due to its high positive charge and relatively large size, an alpha particle has limited penetrating power and can be effectively stopped by a sheet of paper or a few centimeters of air, but it can cause significant damage to living tissue if emitted from a radioactive source inside the body. Although an alpha particle is large compared to other nuclear particles, its charge and mass render it less capable of ionizing atoms or molecules in comparison to other forms of radiation, such as beta particles or gamma rays. However, when an alpha particle does cause ionization, its high electric charge can result in disruptive effects on the chemical structures of cells and DNA, making it potentially harmful to human health.
Scientists have extensively studied alpha particles to better understand their properties and potential applications. This knowledge has led to the development of various scientific techniques, such as the use of alpha particles for medical treatments, imaging, and material analysis.

Etymology of ALPHA PARTICLE
The word "alpha particle" has its etymology rooted in the Greek alphabet. The term "alpha" comes from the first letter of the Greek alphabet, which is "α" (pronounced as "alpha"). The name was chosen because alpha particles are positively charged and have the highest mass among common types of radioactive particles, hence the association with the first letter of the alphabet. This term was coined by British physicist Ernest Rutherford in the early 20th century during his research on radioactivity.
