What is Radiation?

Radiation is a form of energy that may be carried by a stream of particles (i.e., particulate radiation) or by waves (i.e., electromagnetic radiation).

  1. Particulate radiation consists of tiny, fast-moving particles that have energy and mass. This type of radiation is produced by the disintegration of radioactive elements leading to the generation of neutrons and beta particles.1,2,3,4
  2. Electromagnetic radiation is mainly pure energy with no mass that travels through space and matter as waves at the speed of light in stream of small "packets" of energy called photons.1,2,3,4
