noun
- 1. the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.

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)
6 days ago · 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.
a form of energy that comes from a nuclear reaction and that can be very dangerous to health: Many servicemen suffered radiation sickness after the early atomic tests. energy from heat or light that you cannot see: microwave / ultraviolet / electromagnetic radiation. Fewer examples. The radiation leak has had a disastrous effect on the environment.
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.
1. a. : the action or process of radiating. b. : the process of emitting radiant energy in the form of waves or particles. c (1) : the combined processes of emission, transmission, and absorption of radiant energy. (2) : the transfer of heat by radiation compare conduction, convection. 2. a. : something that is radiated. b.
Streams of photons, electrons, small nuclei, or other particles. Radiation is given off by a wide variety of processes, such as thermal activity, nuclear reactions (as in fission), and by radioactive decay. The emission or movement of such particles through space or a medium, such as air.
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.
