Electric & magnetic fields.

According to the National Institute of Environmental Health Services:

“Electric and magnetic fields (EMFs) are invisible areas of energy, often referred to as radiation, that are associated with the use of electrical power and various forms of natural and man-made lighting. EMFs are typically characterized by wavelength or frequency into one of two radioactive categories:

  • Non-ionizing: low-level radiation which is generally perceived as harmless to humans
  • Ionizing: high-level radiation which has the potential for cellular and DNA damage”


Radiation Type Definition Forms of Radiation Source Examples
Non-Ionizing Low to mid-frequency radiation which is generally perceived as harmless due to its lack of potency.
  • Extremely Low Frequency (ELF)
  • Radiofrequency (RF)
  • Microwaves
  • Visual Light
  • Microwave ovens
  • Computers
  • House energy smart meters
  • Wireless (wifi) networks
  • Cell Phones
  • Bluetooth devices
  • Power lines
  • MRIs
Ionizing Mid to high-frequency radiation which can, under certain circumstances, lead to cellular and or DNA damage with prolonged exposure.
  • Ultraviolet (UV)
  • X-Rays
  • Gamma
  • Ultraviolet light
  • X-Rays ranging from 30 * 1016 Hz to 30 * 1019 Hz
  • Some gamma rays

As you can see in the above list, we are continually exposed (in some form) to EMF.  With the widespread use of wireless networks (Wi-Fi), smart meters, cell phones, computers, tablets, and Bluetooth devices, and in an ever-increasing number – we finds ourselves surrounded by EMF.  Some folks believe even the low-level (Non-Ionizing) categories are a danger (especially to younger children), and some have claimed to been harmed by them (as in cancer).  Who knows for sure?

Definitely something to think about…
