Hey there!
Radiation are the way in which Energy moves from one place to another or Emission or transmission of energy in the form of waves or particles through space or through a material medium.
This includes: electromagnetic radiation, such as radio waves, microwaves, visible light, x-rays, and gamma radiation.
For Example-
★ The energy released when a stone is dropped into water radiates away in circular waves.
★ Sound energy radiates from a speaker's mouth to a listener's ear.
★ Light and heat energy radiate from the sun to the earth.
★ Electrons, radiating from a hot wire, provide the energy that forms the picture in a television set.
WHY RADIATIONS ARE PRODUCED??
Every atom is composed of a tiny, positively charged "nucleus" surrounded by a cloud or swarm of negative electrons.
When certain atomic nuclei, notably those of uranium and plutonium, are struck by neutrons, they do not radiate in the usual way.
Instead, they split into two roughly equal parts and give off a large burst of energy.
