WEBRadiation includes particles and electromagnetic waves that are emitted by some materials and carry energy. The kind of radiation discussed below is called ionising radiation because it can produce charged particles (or ions) in matter. X-rays, gamma-rays, alpha particles, beta particles and neutrons are all examples of ionising radiation.

WEBRadiation is energy that travels in the form of waves (electromagnetic radiation) or high-speed particles (particulate radiation). Particulate radiation happens when an unstable (or radioactive) atom disintegrates. Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves.
