Quizplus · Accepted Answer

Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei, such as potassium-40. They are indeed electrons (or positrons) that can travel at speeds up to 90-95% the speed of light, distinguishing them from alpha particles, gamma rays, and neutrons in this context.
