BETA RAYS Meaning and
Definition
-
Beta rays, also known as beta particles, refer to subatomic particles emitted during the radioactive decay of certain atomic nuclei. Specifically, beta rays consist of electrons (β-) or positrons (β+) that are released from the nucleus of an atom.
When an atom undergoes radioactive decay, it may transform into a different element by emitting either an electron or a positron. In the case of β- decay, a neutron within the nucleus is converted to a proton, releasing an electron and an anti-neutrino in the process. This electron, as part of the beta rays, carries a negative charge and is ejected from the nucleus at high speeds. On the other hand, in β+ decay, a proton within the nucleus is converted into a neutron, thereby releasing a positron and a neutrino. The positron, carrying a positive charge, is also emitted from the nucleus as part of the beta rays.
Due to their charge, beta rays can be deflected by electric and magnetic fields, and their paths can be tracked. They possess relatively high energies compared to alpha particles but lower energies compared to gamma rays. Additionally, beta rays are ionizing radiation, meaning they have the ability to strip electrons from atoms they interact with, potentially causing biological damage.
Beta particles are commonly encountered in various applications such as medical imaging, radiation therapy, and nuclear research. Their distinct properties, including their ability to penetrate certain materials and be easily measured, make them valuable for scientific investigation and technological advancements.

Etymology of BETA RAYS
The term "Beta rays" is derived from the Greek alphabet, specifically the second letter, "beta" (β). In the late 19th century, during the discovery and study of radioactivity, scientists observed that there were three types of radiation emitted by radioactive substances. These types were named alpha, beta, and gamma rays, with each type possessing different properties. The choice of the term "beta" for the second type of radiation was likely influenced by the use of the Greek alphabet as a common system for naming and classifying scientific discoveries.
