At Einstein brain, our goal is to protect as many people as possible from the harmful effects of man-made radiation. It all starts with understanding this topic.

Did you know that in 2019 we were exposed to 350 times more electromagnetic radiation than in 2005? And scientists expect this number will double (700 times exposure) or even triple (over 1000 times exposure) when 5G is fully rolled out.

It’s our mission to spread the news that protection and prevention are possible. You can read more about it, including scientific proofs here.

1.What is an electric and magnetic field?

Electric and magnetic fields are areas of energy (also called radiation) that are produced by electricity. It is the movement of electrons, or current, through a wire.

Electric and Magnetic fields are invisible but measurable (with specific meters)

  1. An electric field is produced by voltage, which is the pressure used to push the electrons through the wire, compare it with water being pushed through a pipe.  When the voltage increases, the electric field increases in strength. Electric fields are measured in volts per meter (V/m).
  2. A magnetic field results from the flow of current through wires or electrical devices. The magnetic field increases in strength as the current increases. The strength of a magnetic field decreases rapidly with increasing distance from its source. Magnetic fields are measured in microteslas (μT, or millionths of a tesla).
  3. Electric fields are produced whether or not a device is turned on. Magnetic fields are produced only when the current is flowing, which usually requires a device to be turned on.

Power lines produce magnetic fields continuously because current is always flowing through them.

Electric fields are easily shielded or weakened by walls and other objects, but magnetic fields can pass through buildings, living things, and most other materials.

Electric and magnetic fields together are also known as electromagnetic fields or EMFs.

  1. The electric and magnetic forces in EMFs are caused by electromagnetic radiation.

There are two main categories of EMFs: Ionizing and non-ionizing.

  • Ionizing radiation :
  • Non-ionizing radiation :
  • Low- to mid-frequency EMFs, include static fields, magnetic fields from electric power lines and electronic devices, radio waves, microwaves, infrared radiation, and visible light. The low to Mid-frequency EMFs are in the non-ionizing radiation part of the electromagnetic spectrum and are not known to damage DNA or cells directly.
  • Extremely low-frequency EMFs (ELF-EMFs) and radiofrequency EMFs are included in the Low- to mid-frequency EMFs. ELF-EMFs have frequencies of up to 300 cycles per second, or hertz (Hz), and radiofrequency EMFs range from 3 kilohertz (3 kHz, or 3,000 Hz) to 300 gigahertz (300 GHz, or 300 billion Hz). Radiofrequency radiation is measured in watts per meter squared (W/m2).

2.What types of non-ionizing EMF are there?

There are 2 types of non-ionizing EMF: natural and human-made

  1. Natural non-ionizing EMF

The earth's magnetic field causes a compass needle to orient in a North-South direction and is used by birds and fish for navigation.

Other examples are the static electric field and the Schumann resonance.

Natural mainly refers to electromagnetic radiation (EMR) from the sun, but the light from lamps, flames and infrared sources also belong to this category.

  1. Human-made non-ionizing EMF

We can divide human-made non-ionizing EMF into 2 categories:  extreme low frequency (ELF) and radiofrequency (RF)

These EMFs can come from several sources. 

  1. Extremely low-frequency EMF (ELF-EMF). Sources of ELF-EMF include power lines, electrical wiring, and electrical appliances such as shavers, hairdryers, and electric blankets.
  2.  Radiofrequency radiation. The most common sources of radiofrequency radiation are wireless telecommunication devices and equipment, including cell phones, smart meters, and portable wireless devices, such as tablets, laptop computers, baby monitors etc.

 Einstein Brain Electromagnetic Radiations

Other common sources of radiofrequency radiation include:

  • Radio and television signals. AM/FM radios and older VHF/UHF televisions operate at lower radio frequencies than cell phones. Radio signals are AM (amplitude-modulated) or FM (frequency-modulated). AM radio is used for broadcasting over very long distances, whereas FM radio covers more localized areas. AM signals are transmitted from large arrays of antennas that are placed at high elevation. These sites are off-limits to the general public because exposures close to the source can be high. Maintenance workers who come close to the antennas could receive substantial radiofrequency exposures from AM radio antennas, but the general public would not. FM radio antennas and TV broadcasting antennas, which are much smaller than AM antennas, are generally mounted at the top of high towers.


  • Radar, satellite stations, industrial equipment devices and magnetic resonance imaging (MRI). These operate at somewhat higher radio frequencies than cell phones (1).


  • Microwave ovensused in homes, also operate at higher radio frequencies than cell phones (1). Microwave ovens are manufactured with effective shielding that (when they are qualitatively made) should reduce the leakage of radiofrequency radiation from these appliances.


  • Cordless telephones, which can operate on analogue or DECT (Digital Enhanced Cordless Telecommunications) technology and typically emit radio frequencies similar to those of cell phones. Cell phone base stations.Antenna towers or base stations, including those for mobile phone networks for broadcasting for radio for television, emit various types of radiofrequency (RF) energy. The strength of these exposures varies based on the population density of the region, the average distance from the source, and the time of day or the day of the week (lower exposures on the weekends or at night) (1). In general, exposures decrease with increasing distance from the source (2).


  • Televisions and computer screensproduce electric and magnetic fields at various frequencies, as well as static electric fields. The liquid crystal displays found in some laptop and desktop computers do not produce substantial electric or magnetic fields. Modern computers have conductive screens that reduce static fields produced by the screen to normal background levels.


  • Wireless local area networks, commonly known as Wi-Fi. These are specific types of wireless networking systems and an increasingly common source of radiofrequency radiation. Wireless networks use radio wavesto connect Wi-Fi–enabled devices to an access point that is connected to the internet, either physically or through some form of a data connection. Most Wi-Fi devices operate at radio frequencies that are broadly similar to cell phones, typically 2.4 to 2.5 GHz, although in recent years Wi-Fi devices that operate at somewhat higher frequencies (5, 5.3, or 5.8 GHz) have appeared (3).


  • Digital electric and gas meters, also known as “smart meters.”These devices, which operate at about the same radio frequencies as cell phones, transmit information on the consumption of electricity or gas to utility companies.


For household appliances and other devices that require electricity, magnetic field levels are highest near the source of the field and decrease rapidly the farther away the user is from the source. Magnetic fields drop precipitously at a distance of about 30 cm (1 foot) from most appliances. For computer screens, at a distance of 30 – 50 cm (12–20 inches).

Power lines and electrical appliances that emit non-ionizing EMFs are present everywhere in homes and workplaces. For example, wireless local networks are nearly always “on” and are increasingly commonplace in homes, schools, and many public places.

Many studies have examined the association between non-ionizing EMF exposure and cancer in adults, of which few studies have reported evidence of increased risk (1).


3.The difference between Man-made and Natural EMF/EMR, regarding Biological Activity (Human, animal, nature).

This research has been done by Dr Leendert Vriens, The Netherlands.

In this summary is explained why the weak low-frequency (LF) electromagnetic fields (EMF) from high-voltage lines and domestic appliances and the radio-frequency (RF) EMF/radiation from wireless communication can induce biological effects in our body while the much stronger natural electromagnetic radiation (EMR), such as from the sun, cannot do so.

As far as physics is concerned there are two reasons:

  1. The man-made LF EMF and RF EMF/radiation yield macroscopic field strengths, while the field strength of the natural EMR is equal to zero at all frequencies

  2. The man-made LF magnetic fields and RF-EMF penetrate our body and the RF-EMF are largely absorbed by the body, while most of the natural EMR from the sun does NOT penetrate through our skin.

The man-made EMF thus induce currents, resonant interactions and interferences – involving charged and polar particles and surfaces and magnetic particles - in our body.

=> These interactions and the absorption can lead to harmful biological processes and interference with the biological processes already going on.

The natural EMR from the sun, but the light from lamps, flames and infrared sources also belong to this category. There are also natural EMF, the main ones being the static electric field between the ionosphere and the earth, the static magnetic field from the earth and the Schumann resonance EMF, with higher harmonics, resulting from lightning.  Although EMR having a much higher intensity, does not have any effect inside. Most of it does not penetrate our skin and the part that penetrates has field strengths equal to zero and therefore does not exert any force.

On a microscopic scale, natural EMF is very common. Our body is full of it, think of EEG’s (measuring the electrical activity of the brain) and ECG’s (recording of the electrical activity of the heart muscle).

The microscopic natural EMF inside our body can and will be disturbed by the man-made EMF which penetrate our body. These can by induced currents, resonant interactions, interferences and absorption lead to harmful biological processes and harmful interference with biological processes already going on.

Saying that the RF radiation from wireless communication cannot do any harm because the individual photon energies are not large enough is the same as saying that a tsunami cannot cause any harm because the individual water molecules don’t have enough energy. -Dr Leendert Vriens

4.What do expert organizations conclude about EMF?

In 2002, the International Agency for Research on Cancer (IARC), a component of the World Health Organization, appointed an expert Working Group to review all available evidence on static and extremely low frequency electric and magnetic fields (4). The Working Group classified ELF-EMF as “possibly carcinogenic to humans”.

In 2015, the European Commission Scientific Committee on Emerging and Newly Identified Health Risks reviewed electromagnetic fields in general, as well as cell phones in particular. It found that, overall, epidemiologic studies of extremely low-frequency fields show an increased risk of childhood leukaemia with estimated daily average exposures above 0.3 to 0.4 μT.


 The world is changing without your permission.

When physicians were asked about Electro-Magnetic Radi­ation, about 96% of them believed that EMF radiation can cause illnesses. (EMF Hypersensitivity research, WHO 2006)

More and more people (+/- 35 % of the population) experience mild symptoms like headaches, muscle pains, ear ringings or sleep disturbances.

EMF pollution can also cause health problems like diabetes, inflammation, decreased or complete fertility, insomnia, fatigue, ADHD hormonal problems, panic syndrome, various tumours, childhood leukaemia, electromagnetic hypersen­sitivity and in extreme cases even heart problems or DNA mutation.

Albert Einstein said that “Intellectuals solve problems, geniuses prevent them.”

It is everybody's responsibility to pay attention to their bodies and prevent the harmful effects of EMF radiation on their health.

At Einstein Brain, we have a solution against Electrosmog. We work with scientists who developed a revolutionary pocket-sized product. The Einstein Brain Card.
You can keep it with your phone, laptop or other electronic devices and the card will absorb excess radiation then transform it to light heat. The card uses a patented technology that still allows your devices to fully function, only their radiation level will be reduced within the healthy SAR levels.
