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.
Beta particles are high-energy, high-speed electrons or positrons emitted by certain fission fragments or certain primordial radioactive nuclei such as potassium-40. The beta particles are a form of ionizing radiation, also known as beta rays. The production of beta particles is termed beta decay.
beta particle, electron (unit negative charge) or positron (unit positive charge) spontaneously emitted by certain unstable atomic nuclei in the radioactive disintegration process of beta decay (q.v.). Science Physics Matter & Energy.
8 Μαρ 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.
19 Μαρ 2020 · There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
Property 1: Beta particles (β – particles) are fast-moving electrons or positrons with high energy emitted by the radioactive decay of an atomic nucleus. Property 2: Penetrating power of beta particles is higher than α-particles. They can penetrate through a thin metal foil.
The beta particles are a form of ionizing radiation, also known as beta rays. The production of beta particles is termed beta decay. There are two forms of beta decay: the electron decay (β− decay), the positron decay (β+ decay).
