What is particulate radiation?

Particulate radiation is radiation that comes as actual matter particles with mass. These tiny particles, such as alpha particles (helium nuclei) and beta particles (electrons or positrons), move at high speed in roughly straight lines through matter. They carry charge and cause ionization along their path, and their range in a material depends on their energy and the material they traverse. This is different from electromagnetic radiation, which is energy that travels as waves or as massless photons. Photons are the quanta of light and other EM waves, and they don’t have rest mass, so they don’t move as massive particles along a straight line in the same way.
