➢For high speed electron (more than 1 MeV) more energy
may be lost in the form of X-rays due to interaction with the
nuclear field in dense material (bremsstrahlung).
➢Produce less ionization per unit length than alpha particles
because of its smaller mass and charge.
➢Have greater range than alpha hence, depending on its
energy constitute an external hazard.
➢Not as great an internal hazard as alpha particles.
