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 and the matter with which it interacts and ...
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. Most of this radiation carries no risk to our ...
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 consisting of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) particle radiation consisting of ...
Ionizing radiation is a specific type of radiation that has enough energy to eject an electron from some atom.This radiation includes ionizing particles from alpha or beta decay, as well as electromagnetic waves in the form of gamma radiation.
Apr 16, 2024 · Key Takeaways. 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.
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. The nucleus carries a positive electrical charge, while ...
