noun
- 1. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
- 2. divergence out from a central point, in particular evolution from an ancestral animal or plant group into a variety of new forms: "evolution is a process of radiation not progression"

In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. [1] [2] This includes: electromagnetic radiation consists of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)
Jan 25, 2023 · Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of radiation include the sun, microwave ovens in our kitchens and the radios we listen to in our cars.
Radiation, flow of atomic and subatomic particles and of waves, such as those that characterize heat rays, light rays, and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of 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.
Radiation is energy or particles from a source that travel through space or other mediums. People are exposed to radiation from natural and artificial sources.
Mar 20, 2020 · Radiation is energy given off by matter in the form of rays or high-speed particles. All matter is composed of atoms. Atoms are made up of various parts; the nucleus contains minute particles called protons and neutrons, and the atom's outer shell contains other particles called electrons.
Radiation is energy that travels in the form of waves or particles and is part of our everyday environment. People are exposed to radiation from cosmic rays, as well as to radioactive materials found in the soil, water, food, air and also inside the body.
introduction. 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.
Apr 16, 2024 · Radiation is the emission and transmission of energy in the form of electromagnetic waves or particles. Radiation can be ionizing or nonionizing radiation, and only ionizing radiation has enough energy to potentially cause damage to cells and DNA.
Dec 8, 2019 · Radiation is the emission and propagation of energy in the form of waves, rays or particles. There are three main types of radiation: Read More. Guide to Understanding Radiation's Broad Spectrum. By Anne Marie Helmenstine, Ph.D. Non-ionizing radiation: This is the release of energy from the lower-energy region of the electromagnetic spectrum.
