Define Beta Particles And Write A Short Note On Them.

Beta particles (also referred to as beta radiation or beta rays, denoted by the symbol β) can be defined as positrons or electrons of extremely high speeds that hold extremely high levels of energy. Beta particles usually originate from the radioactive decay of atomic nuclei and the process through which they are created is called beta decay. The two primary types of beta decay are β+ decay (which involves the emission of positrons) and β- decay (which involves the emission of electrons). It is important to note that beta rays are a form of ionizing radiation and are capable of knocking electrons out of atomic nuclei (owing to their high energies and high speed or momentum).
