BETA PARTICLES Meaning and
Definition
-
Beta particles are subatomic particles that are often emitted during the process of radioactivity. These particles are electrically charged and can take the form of either electrons or positrons. When an unstable atomic nucleus undergoes beta decay, it either emits an electron (beta-negative decay) or a positron (beta-positive decay) to achieve a more stable state.
Beta particles are distinct from alpha particles, which consist of helium nuclei, and gamma rays, which are high-energy photons. Unlike alpha particles, which have a greater mass and are positively charged, beta particles are much lighter and negatively or positively charged, depending on the decay process.
These energetic particles travel at high speeds and can penetrate matter to varying degrees depending on their charge, energy, and the medium they pass through. While beta particles can be stopped by a few millimeters of aluminum or a few centimeters of plastic, they can cause damage to living tissue if absorbed by the body.
The emission of beta particles plays a crucial role in various fields of study, including nuclear physics, medicine, and industry. They are employed in medical imaging techniques such as positron emission tomography (PET), where positrons are used to create detailed images of organs and tissues. Beta particles are also utilized in industrial applications like thickness gauges and quality control measures for determining the density and thickness of certain materials.
In summary, beta particles are charged subatomic particles emitted during radioactive decay, which can be either electrons or positrons. They play a significant role in scientific research and are utilized in various applications across different disciplines.

Etymology of BETA PARTICLES
The word "beta" is derived from the second letter of the Greek alphabet, β (beta). In the context of radiation, "beta" refers to beta particles, which are high-energy, high-speed electrons or positrons emitted by certain types of radioactive decay. The term "beta" was coined in the early 20th century by Ernest Rutherford to describe this type of radiation.
