A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus, known as beta decay. There are two forms of beta decay, β − decay and β + decay, which produce electrons and positrons, respectively. [2]
Nuclear chemistry is the study of the breakup of unstable nuclei, which results in the emission of radiation and energy. There are three types of radiation; alpha (α), beta (β) and gamma (γ).
Radiation caused by beta particles (high-energy electrons). A beta particle is an electron ejected from a nucleus when a neutron becomes a proton. A beta particle has a relative mass of...

Key characteristics of beta radiation are summarized in the following points: 1. Beta particles are energetic electrons. They are relatively light and carry a single negative charge. 2. Their mass is equal to the mass of the orbital electrons with which they are interacting. A much larger fraction of its kinetic energy can be lost in a single inter...
Beta-decay or β decay represents the disintegration of a parent nucleus to a daughter through the emission of the beta particle. If a nucleus emits a beta particle, it loses an electron (or positron). In this case, the mass number of the daughter nucleus remains the same, but the daughter nucleus will form a different element. Beta decay is governe...
For photon and electron radiation, the radiation weighting factor has the value 1 independently of the energy of the radiation, and for alpha radiation, the value 20. For neutron radiation, the value is energy-dependent and amounts to 5 to 20. Beta particles(electrons) are much smaller than alpha particles. They carry a single negative charge. They...
Beta radiation ionizes matter weaker than alpha radiation. On the other hand, the ranges of beta particles are longerand depend strongly on the initial kinetic energy of a particle. Some have enough energy to be of concern regarding external exposure. A 1 MeV beta particle can travel approximately 3.5 meters in the air. Such beta particles can pene...
The coulomb forces that constitute the major mechanism of energy loss for electrons are present for either positive or negative charge on the particle and constitute the major mechanism of energy loss also for positrons. Whatever the interaction involves a repulsive or attractive force between the incident particle and orbital electron (or atomic n...
Sep 2, 2024 · Beta decay is a type of radioactive decay where an unstable atom releases a high-energy, fast-moving particle to become more stable. The particle emitted during a beta decay is known as a beta particle, which can be an electron or a positron. This radiation process changes one element into another by altering the number of protons in the nucleus.
Beta particles are high energy electrons or positrons that are ejected from the nucleus by some radionuclides during beta-decay. They have a small mass, a haphazard path and can cause burns or damage to internal cells and organs.
Mar 8, 2019 · A beta particle (β) is a high-energy electron or positron shot out due to a radioactive event. Beta rays or beta radiation is a form of ionizing radiation emitted by certain types of radioactive nuclei.
