Examples of somatic radiation damage include skin burns and cataracts caused by exposure to ionizing radiation.
Examples of matter: water, air, iron. Non-examples of matter: light, sound, thoughts.
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 substances that do not follow the particle model include light and electromagnetic radiation. These entities exhibit wave-like behavior and are not composed of particles in the same way as matter.
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: Electromagnetic radiation with high energy used in medical diagnostics. Gamma rays: High-energy electromagnetic radiation emitted from atomic nuclei. UV radiation: Ultraviolet radiation from the Sun that can cause sunburn and skin damage.
A banana is a non-example of radiation.
