Explain the nature and behaviour of beta radiat... - SS2 Physics Modern Physics - Nuclear Physics Question

Beta radiation consists of high-speed electrons or positrons. Beta particles can be negatively charged (electrons) or positively charged (positrons). They have a much smaller mass compared to alpha particles, and therefore, they have greater penetrating power. Beta particles can be deflected by electric and magnetic fields and can travel several metres in the air. They have moderate ionising power and can penetrate into living tissues, causing damage.
