This site was designed to inform you about our topic: radiation. Radiation
can be defined as the process of emitting energy in the form of waves or particles. Various types of radiation may be distinguished, depending on the properties of the emitted energy/matter,
the type of the emission source, properties and purposes of the emission, etc. When used by the general public, the word "radiation" commonly refers to non-ionization and electromagnetic radiation.

Nonionizing radiation includes ultraviolet light, infrared radiation, microwaves, and radio frequencies, all of which
are electromagnetic waves. The toxicity of radio frequencies is rather low. On the whole, nonionizing radiation is not as
toxic as ionizing radiation, and the various forms of nonionization radiation share common target organs.
Electromagnetic radiation is generally described as a self-propogating wave in space with electric and magnetic energies.
Electromagnetic radiation is classified into types according to the frequency of the wave. These types include: radio waves,
microwaves, infrared radiation, visible light, ultraviolent light, X-rays, and gamma rays. The electromagnetic radiation carries
energy and momentum, which may be imparted when it interacts wth matter.
Electromagnetic waves of much lower frequency than visible light were first predicted by Maxwell's equations and subsequently
discovered by Heinrich Hertz. Maxwell derived a wave form of the electric adn magnetic equations, revealing the wavelike nature
of electric and magnetic fields and their symmetry.
