Radiation is energy that is emitted or transmitted in the form of waves or particles through space or through a material medium.
It can take the form of sound, heat, or light, but is most commonly used to refer to radiation from electromagnetic waves, ranging from radio waves to gamma waves.
All matter is composed of atoms, which are made up of protons, neutrons, and electrons.
We are exposed to radiation in our everyday life from sources such as the sun, microwave ovens, and radios.

What is Radiation? | IAEA - International Atomic Energy Agency
Radiation is the process by which energy is emitted as either particles or waves. Broadly, it can take the form of sound, heat, or light. However, most people generally use it to refer to radiation from electromagnetic waves, ranging from radio waves, though the visible light spectrum, and up through to gamma waves.
