What is EMR and EMF? And, what is the Electromagnetic Spectrum?

  • EMR stands for Electromagnetic Radiation.
  • EMF stands for Electromagnetic Field.

What is the difference between EMR and EMF?
Charged particles such as electrons and protons create electromagnetic fields (EMF) when they move. These fields transport the type of energy we call electromagnetic radiation (EMR).

What is the Electromagnetic Spectrum?

The Electromagnetic Spectrum is the range of  electromagnetic radiation, sinusoidal waves in motion that spread out as it travels. These waves (think ocean) have a frequency, that is, how many waves occur each second. Electromagnetic frequency is measured in Hertz (HZ), or cycles per second. If you think about the ocean, the higher the top of the wave, the more powerful the wave is. This is the same with the waves in the electromagnetic spectrum. The distance between the waves  is called the wavelength. So, as the frequency increases, the wavelength decreases proportionately and vice-versa. The Electromagnetic Spectrum is arranged according to frequency and wavelength, from smallest frequency to highest. and as such, from longest wavelength to shortest. And, all of these waves move through space at the speed of light!

Natural vs. Man-Made Electromagnetic Radiation

There is electromagnetic radiation that comes from nature. For example, the sun, earth, and other bodies radiate electromagnetic energy of varying frequencies and wavelengths. At the very low end, under 1 Hz, is geomagnetic pulsations, ultra-low-frequencies (ULF). At the very high end is gamma rays. In between is visible light which falls between infrared (IR) and ultraviolet (UV). Visible light has frequencies of about 400 to 800 trillion cycles per second (Hz). And, it has wavelengths of about 740 to 380 nanometers (nm – billionths of a meter).

Also, there is man-made electromagnetic radiation. For example, the electricity in our homes travels at 60 Hertz (Hz) in North America (50 Hz in Europe). Radio waves start at 3 kilo-hertz (3,000 cycles per second) and go up as high as 1 Giga-hertz (1 billion cycles per second). Microwaves go from about 1 Giga-Hertz to 300 Giga-Hertz.

What is Ionizing Radiation and Non-Ionizing Radiation? And, what is the difference between them?

The Electromagnetic Spectrum can be divided into two parts.

  1. Ionizing Radiation is a type of high-energy radiation. Ionizing radiation has enough energy to remove an electron (negative particle) from an atom or molecule. In other words, it becomes ionized. Examples of ionizing radiation are X-rays and Gamma Rays (frequencies above that of ultraviolet light).
  2. Non-Ionizing Radiation is a type of low-energy radiation. Non-ionizing radiation does not have enough energy to remove an electron (negative particle) from an atom or molecule. Examples of non-ionizing radiation are visible, infrared light, microwaves, radio waves, and radiofrequency energy from cell phones (visible light and below).

Many government organizations around the world as well as media claim that only ionizing radiation is harmful to our health. However, thousands of peer reviewed studies have proven that non-ionizing radiation can negatively impact our health and life in general.
