Beta radiation

Beta radiation is a type of energy that comes from atoms. Atoms are made up of small particles called protons, neutrons and electrons. When an atom has too many or too few electrons, it can release energy in the form of beta radiation. This radiation is made of tiny particles or waves that travel through the air. Beta radiation can damage living things, such as people and animals, so it is important to be careful around it.
