Electromagnetic Fields Spectrum

We will focus on the most dangerous radiation, that is present in every household, office, school. You will be able to detect it and reduce it to a minimum.

In the picture below you can see the frequencies of harmful radiation fields that are harmful to your health and can be found almost everywhere. Radiation with lowest frequencies are power lines radiations, home appliance radiation, electric wiring inside the house, then more towards the top you can see high-frequency fields that contain wireless radiation, microwave radiation, UMTS radiation, radar frequencies, mobile network radiation……Low-Frequency Fields range from up to 3 kHzhigh-frequency field radius range from 3 kHz to 300 GHz. We will stop before the medical X-ray. They are extremely high frequencies and not present in our homes.

emf and hf fields

Electromagnetic fields are invisible forces of nature, generated by electricity, which are present whenever electricity exists. Since the beginning of the twentieth century, we have been surrounded by a huge spectrum of man-made EM fields due to the fast growth of power line gridsradio and television antennasradarsmobile communications, and various home and office appliances.

Scientists started to research possible bioeffects due to exposure to EM fields after World War II. However, they started to be really concerned in the 1970s. Attention shifted from the strong electric fields emitted by high-voltage power lines to weaker magnetic fields produced by distribution lines that bring electricity to our homes.

Visible light is the range of the spectrum where our eyes are able to compute waves into images. The rest of the spectrum that isn’t visible to the naked eye can be divided into two categories: ionizing and non-ionizing radiation. Visible light can be thought of as a dividing line between these two types of radiation…

Interesting facts

  • Every country in the world runs electricity on frequencies from 50 hertz to 60 hertz. This means the electric waves are moving 50–60 times per second.
  • Mobile phones use frequencies around 900 MHz to 1900 MHz. The waves, in this case, move at a rate of 900,000,000 to 1,900,000,000 times per second
  • Wi-Fi uses a frequency of 2.4 GHz and 5Ghz, which means the waves move 2,450,000,000 or 5,000,000,000 times per second
  • 5G network will use much higher frequencies such as 29 GHz and even higher, which means 5G waves are moving 29,000,000,000 per second
  • The planned 7G will use super-high frequencies of up to 3 THz which means waves will be moving 3,000,000,000,000 per second.

More Details About Electromagnetic Fields

Wherever electricity is used, generated, transmitted, distributed, electromagnetic fields are generated, often at significant intensities. In most cases, electric and magnetic fields can’t be seen or felt, but they can be measured with special electromagnetic measuring equipment. Only some people are sensitive to electromagnetic fields, and they can feel them.

Every wire or conductor that carries electricity, is surrounded by both electric and magnetic fields. These fields often extend for substantial distances around the wire.

Significant magnetic fields come from sources such as transmission and distribution lines, substations, transformers, network protectors, feeders, switch gears, distribution busways, electric panels, wiring systems, motors, and various electric appliances. Magnetic fields can be very strong and can easily penetrate materials, like people, buildings, and most metals. Magnetic fields are strongest near the source but diminish fast with distance. Commonly, units used for measurements are either microteslas (gT) milligauss (mG).

ELECTROMAGNETIC fields consist of:

  1. ELF FIELDS – Extreme low-frequency electromagnetic fields – frequencies up to 3 kHz
  2. RADIO FREQUENCY FIELDS – High-frequency radiation fields – frequency range of 3 kHz to 300 GHz

On the following pages, you will be able to learn more about each frequency field. You will understand why they are dangerous. And also you will be able to protect yourself with my help and expertise.
