A type of ionising radiation. A high energy electron from the nucleus

Beta radiation is blocked by a few mm of aluminium. Each beta particle (a high energy electron) has a charge of -1 and a relative mass of 0. Beta radiation is released from the nucleus when a neutron turns into a proton and emits an electron in the process.
