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.
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)
25 Ιαν 2023 · Radiation is energy that moves in waves or particles. It can be beneficial or harmful depending on the type, dose and source. Learn about non-ionizing and ionizing radiation, radioactive decay, and how to protect yourself and the environment.
16 Απρ 2024 · Radiation is the emission and transmission of energy in the form of waves or particles. Learn about the electromagnetic spectrum, ionizing and nonionizing radiation, sources of radiation and how to protect yourself from harmful exposure.
7 Ιουλ 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.
Learn about the different forms, sources, and effects of radiation from the U.S. Nuclear Regulatory Commission. Find out how radiation is used in medicine, industry, and energy production.
