Web1. Sun. One of the most important sources of energy is the Sun. The cosmic radiation emitted from the Sun is a mixture of electromagnetic waves; which range from infrared (IR) to ultraviolet rays (UV). In addition, it also emits visible light. Most of the radiation emitted by the Sun is absorbed by the atmosphere.

What is Radiation? | IAEA - International Atomic Energy Agency
WebJan 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 ...
Webelectromagnetic radiation consists of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) particle radiation consists of particles of non-zero rest energy, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation.
WebJul 18, 2023 · Examples of this kind of radiation are radio waves, visible light and microwaves. Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes.
WebDec 8, 2019 · Examples include: A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles. Uranium-238 decaying into Thorium-234 emits radiation in the form ofalpha particles. Electrons dropping from one energy state to a lower state emit radiation in the form of a photon.
