Particulate: Beta ( ) and Positron ( )

-

➢High speed electrons emitted by a radionuclide.

➢Either be positive (positron) or negative (electrons).

➢Not emitted with discrete energies but show a continuous

energy spectrum (unlike alphas).

➢Lose energy more frequently through ionization and excitation.

➢Directly ionizing particles - cause ionization of an atom without

any intermediate interaction taking place.
