ANSWER: 1, 2
- A beta particle, sometimes called beta ray, denoted by the lower-case Greek letter beta (β), is a high-energy, high-speed electron or positron emitted in the radioactive decay of an atomic nucleus, such as a potassium-40 nucleus, in the process of beta decay.
- Two forms of beta decay, β- and β+, respectively produce electrons and positrons.
- Beta particles are a type of ionizing radiation.
