Radiation can be described as energy or particles from a source that travels through space or other mediums. Light, heat, microwaves and wireless communications are all forms of radiation. This includes the following: Particle Radiation: such as alpha radiation (α), beta radiation (β), and neutron radiation.
Jul 7, 2023 · Radiation is the emission of energy as electromagnetic waves or moving subatomic particles. Natural radiation comes from many naturally occurring radioactive materials found in soil, water, air and in the body. Every day, people inhale and ingest forms of radiation from air, food and water.
Heat radiation (as opposed to particle radiation) is the transfer of internal energy in the form of electromagnetic waves. For most bodies on the Earth, this radiation lies in the infrared region of the electromagnetic spectrum.
Radiation is the term used for all phenomena characterised by the transport of energy, either by waves or sub-atomic particles. The highest energy waves can behave just like particles, and sub-atomic particles can behave just like waves. This is called the wave – particle duality.
Introduction to Radiation. In subjects like physics the topic radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. This includes: The electromagnetic radiation, waves of radio, microwaves, infrared rays, visible light, ultraviolet rays, X-rays and gamma radiation i.e., γ.

Sep 6, 2019 · Radioactivity is the process by which an unstable atomic nucleus loses energy by emitting radiation. While radioactivity results in the release of radiation, not all radiation is produced by radioactive material. The SI unit of radioactivity is the becquerel (Bq). Other units include the curie, gray, and sievert.
