An Overview of the Two Main Types of Electromagnetic Radiation – and Their Common Sources

You may not know much about EMF (and that’s perfectly normal), but chances are you are sitting in an area in which there is EMF right now, and chances are that you are getting bombarded by the harmful radiation at this very moment. The good news is that there’s no need to panic (for the moment). The bad news is that it is indeed time to get informed, and see what you can do to protect yourself from it.

Have you ever wondered what exactly EMF is, and why it could be harmful? Here’s an overview of the two main types of electromagnetic radiation – and their common sources.

What is EMF?

EMF – or electro-magnetic frequency – is a frequency we find all around us; it’s created by a magnetic field (such as the one the Earth creates) or such as the ones we create by the millions of electrons that stream through our nervous system. Under normal, natural circumstances, these are completely harmless and pose no risk. However, technology has caused a revolution and we are constantly exposed more and more to EMF, to hazardous levels.

Ionising radiation

Like light and radio waves, EMF belongs to the radiation spectrum. Ionising radiation belongs to the medium to high spectrum, and is mostly caused by:

  • Ultraviolet lights (ultraviolet rays)
  • X-ray machines (x-rays)
  • Gamma ray emitting machines (gamma rays)

As this kind of radiation can seriously interfere with the body on a cellular level, it’s often responsible for cell damage and DNA mutations.

Non-ionising radiation

Non-ionising radiation belongs to the low to medium frequency, and is often caused by:

  • Extreme low frequency (sonar, etc)
  • Radiofrequency (radios, radar, and so on)
  • Microwaves (microwave ovens, and so on)

WiFi and other modern applications also belong to this category.

The major sources


Think of the following:

  • Mobile phones
  • Microwave ovens
  • WiFi points
  • Power lines

Why it is dangerous

Since EMF can seriously interfere with our natural body and the way it functions, prolonged exposure can lead to serious diseases, such as cancer, tumors, migraines, and so on.

The good news is that there are some things you can do – simple things, actually – which will help protect you from the harmful effects of this radiation. Though these actions are fairly simple and straightforward, the fact is that they can make a big difference. For example, rather than calling someone, send an SMS. It reduces the time your mobile phone emits EMF, hence reducing your time of exposure. Similarly, when calling, put it on speaker or use a headset – this will increase the distance between your device and your head (and your brain). You can also use protective devices, such as a specially-made EMF pendant and other types of jewellery. Get informed. Protect yourself.
