Beta particles areelectrons orpositrons emitted by someradioactivenuclei such aspotassium-40 orcarbon-14 (which becomes nitrogen-14).[1] The beta particles emitted are a form ofionizing radiation sometimes called beta rays.Henri Becquerel andErnest Rutherford discovered beta rays in the 1890s. Beta particles are made bybeta decay. When scientists write it in an equation, they are use theGreek letter beta (β). There are two forms of beta decay, β- and β+, which make theelectron and thepositron. β- is a single electron that has a negative charge of -1. Both beta decays also turn aneutron into aproton.
