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 during the process of beta decay. There are two forms of beta decay, β − decay and β + decay, which produce electrons and positrons respectively.
Beta particle. A charged particle (with a mass equal to 1/1837 that of a proton) that is emitted from the nucleus of a radioactive element during radioactive decay (or disintegration) of an unstable atom.A negatively charged beta particle is identical to an electron, while a positively charged beta particle is called a positron.Large amounts of beta radiation may cause skin burns, and beta ...
No, beta decay isn't the same as a beta particle, but a beta particle is emitted in beta decay. There are two kinds of beta decay, and they are beta minus and beta plus decay. In these decay events, an electron and a positron (anti-electron) will be emitted from a nucleus, respectively.
Can aluminum foil stop a beta particle or gamma particle? No, it cannot. Alpha particles can be stopped using aluminum foil. Beta particles (electrons) posses higher kinetic energy and have ...

Alpha particles, also called alpha ray or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus.They are generally produced in the process of alpha decay, but may also be produced in other ways.Alpha particles are named after the first letter in the Greek alphabet, α.The symbol for the alpha particle is α or α 2+.

A negatively charged beta particle is identical to an electron. A positively charged beta particle is called a positron. Exposure to large amounts of beta radiation from external sources may cause skin burns (erythema). Beta emitters can also be harmful if they enter the body. Thin sheets of metal or plastic may stop beta particles.
