A simple example of radiation is to turn on a light-bulb, and bring your hand close to it. The closer your hand gets, you begin to feel the heat from the light bulb. This is radiated heat energy. As soon as you turn on the light-bulb, even before you bring your hand close to it, you SEE it, because of the electromagnetic radiation in the VISIBLE range that leaves it.
Another example of radiation can be a lava lamp. Radiation is the whole reason how a lava lamp works.
Also there is ultraviolet, visible, infrared, gamma, microwave, X, alpha, beta, etc.
Examples of somatic radiation damage include skin burns and cataracts caused by exposure to ionizing radiation.
Two examples of mutagens are ultraviolet radiation, which can cause changes in DNA by creating thymine dimers, and certain chemicals like polycyclic aromatic hydrocarbons found in cigarette smoke, which can interact with DNA and cause mutations.
X-rays and gamma rays are the two types of radiation that can pass through a sheet of card due to their high energy and penetrating abilities.
Polonium-210 primarily emits alpha radiation, which consists of two protons and two neutrons. This type of radiation has a low penetrating power and is highly ionizing, making it hazardous if ingested or inhaled.
Ionizing radiation causes some of the atoms it strikes to be ionized. There are several different types: alpha particles, beta particles, neutrons, gamma rays, x-rays, and ultraviolet light. Non-ionizing radiation, which does not ionize atoms, includes visible light, infrared light, radio waves, and so on.To understand the biological effects of radiation we must first understand the difference between ionizing radiation and non-ionizing radiation. In general, two things can happen when radiation is absorbed by matter: excitation or ionization.Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.Because living tissue is 70-90% water by weight, the dividing line between radiation that excites electrons and radiation that forms ions is often assumed to be equal to the ionization of water: 1216 kJ/mol. Radiation that carries less energy can only excite the water molecule. It is therefore called non-ionizing radiation. Radiation that carries more energy than 1216 kJ/mol can remove an electron from a water molecule, and is therefore called ionizing radiation.Related links are provided below.
Examples of somatic radiation damage include skin burns and cataracts caused by exposure to ionizing radiation.
Irritation or damage to the skin caused by radiation exposure: two examples are sun burn and beta burns.
Two examples of infrared waves are heat radiation emitted by the human body and infrared sensors in TV remotes.
Natural background radiation
Two examples of ultraviolet waves are UVA (long-wave ultraviolet) and UVB (short-wave ultraviolet). UVA radiation can penetrate deeper into the skin and is associated with skin aging, while UVB radiation is responsible for sunburn and can contribute to skin cancer.
A banana is a non-example of radiation.
The sun
Two examples of infrared waves are heat radiation emitted by a fire and the heat you feel from the sun on your skin.

Radiation heat examples include sunlight warming the Earth, a campfire heating a person, and a microwave heating food.
