Answer 1

Answer:

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. You could also call radiation “electromagnetic waves”.

Radiation Definition

Radiation is the emission and propagation of energy in the form of waves, rays or particles. There are three main types of radiation:

Non-ionizing radiation: This is the release of energy from the lower-energy region of the electromagnetic spectrum. Sources of non-ionizing radiation include light, radio, microwaves, infrared (heat), and ultraviolet light.

Ionizing radiation: This is radiation with sufficient energy to remove an electron from an atomic orbital, forming an ion. Ionizing radiation includes x-ray, gamma rays, alpha particles, and beta particles.

Neutrons: Neutrons are particles found in the atomic nucleus. When they break away from the nucleus, they have energy and act as radiation.

Examples of Radiation

Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. Examples include:

A burning candle emits radiation in the form of heat and light.

The Sun emits radiation in the form of light, heat, and particles.

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 photon.
