What are EMFs

Electromagnetic Radiation

The area of Electromagnetic Radiation (EMR) also called Electromagnetic Field (EMF) encompasses many types of man-made energies.  The types of EMR are related to each other by the rate at which each vibrates. The rate of vibration is termed frequency in cycles per second or Hertz. The Electromagnetic (EM) spectrum relates these types of radiation by the frequency of vibration.

What are Electromagnetic Fields?

An AC electromagnetic field, also known as EMF or EM field, is a physical field produced by moving electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The field can be viewed as the combination of an AC electric field and an AC magnetic field. Since it is AC by definition, it continually changes polarity from positive to negative.

AC Electric Field

AC Electric Fields (E-Fields) are produced by the presence what-are-emfsof electricity. Their strength is determined by voltage, the higher the voltage, the stronger the field. AC Electric Fields are generated by live electrical wires and generally travel 6-8 feet from the source, but in some cases further. An electric field will exist even when a device is not in use (turned off). In other words, these sources produce a continual emission. AC Electric Fields have a natural attraction to ground and the human body. They are considered low frequency electromagnetic radiation. (5 Hz – 400,000 Hz). They can be measured with an AC Electric Field meter and the unit of measurement is Volt per meter V/m.

AC Magnetic Fields

Living spaces contain dozens of electronic devices and electrical appliances. When this equipment is active or turned on, a flow of electrical current begins. This flow of electricity through the equipment and wiring is responsible for creating AC Magnetic Fields (B-Fields). The intensity or strength of the magnetic field is directly related to the power consumption of the device. A more powerful device will produce a higher magnetic field. These fields usually remain close to their source (2-3 feet) but can travel several hundred feet; an example is in the case of high voltage power lines. AC Magnetic Fields are considered low frequency electromagnetic radiation. (5 Hz – 400,000 Hz). They can be measured with a tesla meter in nanoTesla (nT) or with a gauss meter in milliGauss mG. Note: An AC Magnetic Field is typically what people refer to as EMF, but this is an inaccurate statement.

Dirty Electricity

Known as MicroSurge Electro Pollution (MEP). Measured in milliVolts, or milligauss or volts per meter.  MEP can be found on both AC Magnetic Fields and AC Electric Fields.  They are prevalent throughout most urban environments. These are frequency transients that couple onto the electrical wire and then emanate from the wiring into the home. They come from all our new technology, appliances and charging devices and can arguably have a strong biological effect on our bodies. The symptoms are similar to the other Electro Magnetic Fields that are described above.

  • Switch mode power supplies
  • All plug in chargers
  • Tvs, computers, networking equipment
  • LED lights
  • Flourescent lights
  • Dimmers (one of the worst)
  • Solar panels
  • Variable speed motors
  • Pool pumps
  • Air conditioners

DC Magnetic Fields

(Earth magnetic or caused by large amounts of metal) is the field that moves the compass.  Measured in milliGauss or nanotesla.

  • Geopathic Stress
  • Iron structural components
  • Spring coil mattress
  • Metal bed frames
  • Magnetic blankets
  • Iron piping

DC Electric Fields

(static electricity typically found on materials) is created when the humidity is low, the air is dry.  It stays charged unless it can be grounded.  We want to avoid this or stay grounded as these devices changes our own charge.

  • Dry air
  • Synthetic materials like polyester and plastic
  • Vinyl decks
  • Polyester carpets
  • Laminate flooring
  • Acrylic paint
  • Fleece
  • Polyester clothing
  • Computer screens, most technology

Radio Frequency

“RF” Waves: The use of Radio Frequency “RF” Wave technology plays an integral part in our daily lives. As AC Electric fields and AC Magnetic fields approach higher frequencies, the fields are airborne and, in this condition, become Radio Waves. Microwaves are simply higher frequency radio waves. RF waves are used to convey information from one place to another through the air. They are used in mobile communication, radio and television broadcasts, radar, satellite navigation, homeland security and are a significant part of what we recognize today as an international communication infrastructure. These high energy, airborne waves, are capable of traveling miles. RF waves are considered high frequency electromagnetic radiation (10 MHz -10000+ MHz). Power density readings in microwatts per square meter µW/m² are often used to express the magnitude of the signals. A spectrum analyzer is used to identify the specific frequency of a signal.

  • Cordless telephone
  • Cell phones (3G,LTE,5G)
  • Wireless Internet(2.4ghz and 5G)
  • Bluetooth
  • Broadcast TV and Digital Broadcast TV
  • Communications and Military Radar
  • AM/FM radio
