electromagnetic radiation

n.
Energy having both the form of electromagnetic waves and the form of a stream of photons and traveling at the speed of light in a vacuum. The entire range of frequencies and wavelengths of electromagnetic radiation makes up the electromagnetic spectrum.

electromagnetic radiation

n
(General Physics) radiation consisting of self-sustaining oscillating electric and magnetic fields at right angles to each other and to the direction of propagation. It does not require a supporting medium and travels through empty space at the speed of light. See also photon

n.
radiation consisting of electromagnetic waves, including radio waves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

electromagnetic radiation

Energy that moves through space and matter both in the form of magnetic and electric waves and in the form of a stream of particles called photons.
Did You Know? Many people have heard that light is made up of waves, but what does that mean? The answer seems very abstract: light, and other forms of electromagnetic radiation, are made up of wave-shaped electric and magnetic fields that reinforce each other as they travel together. In the 19th century, physicists discovered that a changing electric field can create a magnetic field, and a changing magnetic field can create an electric field. So a wave-shaped electric field (for example, the field created when a charged particle such as an electron moves up and down) can create a wave-shaped magnetic field, which in turn reproduces the wave-shaped electric field. These mutually re-creating fields travel at the speed of light. Electromagnetic radiation can have a variety of properties, depending on its wavelength. Certain wavelengths make up the spectrum of visible light. Infrared light and radio waves have longer wavelengths, whereas ultraviolet light, x-rays, and gamma rays have shorter wavelengths. These wave properties do not tell the full story of electromagnetic radiation, however. Visible light and other forms of electromagnetic radiation also exist as streams of the particles known as photons. The energy of the photons increases as the frequency of the waves gets higher.

electromagnetic radiation

Radiation made up of oscillating electric and magnetic fields and propagated with the speed of light. Includes gamma radiation, X-rays, ultraviolet, visible, and infrared radiation, and radar and radio waves.

It is the relative elevation of histamine in response to foods, inhalants, allergens, emotional stressors, and electrosmog that is problematic and causes the allergic phenomena, not the absolute histamine level.

is something new and fresh, they need a history lesson or to stop radiating their brain on the Internet with electrosmog.
Doctors and researchers believe that this dirty electricity or electrosmog can even have fatal effects on human beings whereas according to some, there is a way to thwart the effects of electrosmog.
Since the electromagnetic radiations, also known as electrosmog cannot be seen, smelt or felt, one would not realize their potential harm over long periods of exposure until they manifest in the form of biological disorders.
