Electromagnetic Field – Hazards

There are two known types of EMF exposure. Low-level radiation, also known as non-ionizing radiation which is very mild and considered harmless to people, this type of exposure is from microwaves, mobile phones, Wi-Fi routers, power lines, and MRI’s. High-level radiation is called ionizing radiation, this is the second type and is sent out in the form of ultra violet from the sun, and x-rays. EMF exposure intensity decreases as you increase your distance from the source of exposure. Common sources of EMF are:


  • Microwaves
  • Computers
  • Energy metres
  • Wi-Fi Routers
  • Mobile Phones
  • Bluetooth
  • Power lines
  • MRIs


  • Ultraviolet light
  • X-rays

EMFs are measured in a unit called Volts per metre. The higher the measurement, the stronger the EMF. Most electrical appliances are tested to ensure EMFs fall within the guide lines and are considered harmless. Public utilities and governments are responsible for managing EMFs relatied to power lines, mobile towers, and other sources of EMF.

Symptoms of EMF Exposure

EMFs can affect your bodys nervous system function and cause damage to cells. Cancer and unusual growths may be one symptom of extreme EMF exposure, other symptoms may include:

  • Fatigue
  • Headache
  • Insomnia
  • Depression/ depressive symptoms
  • Dysesthesia
  • Lack of concentration
  • Dizziness
  • Irritability
  • Loss of appetite/Nausea
  • Burning sensation on the skin/ tingling
  • Anxiety

The symptoms are vague and diagnosis from symptoms is unlikely, EMF is still heavily researched and there isn’t enough evidence to suggest many effects on human health. It is better to keep exposure at a minimum and avoid Ionizing radiation where you can.

If you operate, control, or work in an industrial environment, then you must be aware of the EMF requirements and how they can relate to the workplace. As an employer you must assess the levels of EMF where your employees may be exposed, ensure the exposure is below the ALs (action levels), devise and implement a plan to ensure compliance and assess the risks of employees’ exposure and eliminate or reduce those at risk. Sysco Environmental can provide you with the information required to ensure your electromagnetic environment is within limits by an experienced engineer performing a EMF survey, for more information visit Sysco Environmental
