Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties.

Examples:

• ‌Uranium-238 decaying into Thorium-234 emits radiation in the form of alpha particles.
• Electrons dropping from one energy state to a lower state emit radiation in the form of a proton.

The invisible heat rays which transfer heat by radiation are called infra red ray.
