EMF Exposure: Danger Levels, Symptoms, Protection

Electromagnetic fields (EMF) are all around us. They are generated by a variety of sources, including electronic devices and electrical systems. While some EMF sources, such as natural radiation from the sun, are harmless, others can pose a danger to human health, particularly in the workplace.

In this article, we will explore the sources of EMF in the workplace, the danger levels of exposure, common symptoms of EMF exposure, and steps you can take to protect yourself and your colleagues.

Sources of EMF in the Workplace

There are a variety of sources of EMF in the workplace. Some of the most common sources include:

1. Electrical wiring: Electrical wiring in the walls and floors of a building can generate EMF.

2. Lighting systems: Fluorescent lighting systems are a significant source of EMF in the workplace.

3. Computer monitors: The electromagnetic fields generated by computer monitors can be significant, particularly with older CRT monitors.

4. Electronic devices: Electronic devices, such as printers, scanners, and photocopiers, generate significant EMF.

5.Wi-Fi routers and smart meters: Wi-Fi routers generate significant EMF in the workplace, particularly in areas where there are multiple routers.

6. High-voltage power lines and substations: High-voltage power lines near the workplace can also generate significant EMF.

Danger Levels of EMF Exposure

The danger levels of EMF exposure depend on a variety of factors, including the strength of the EMF, the frequency of the EMF, and the length of exposure. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) provides guidelines for exposure to EMF. These guidelines are designed to protect workers from the harmful effects of EMF.

The ICNIRP guidelines set limits on exposure to EMF based on the frequency of the EMF. For example, the guideline for exposure to EMF at a frequency of 50 Hz, which is the frequency of AC power systems, is 360 microtesla (μT) for occupational exposure and 100 μT for general public exposure.

Symptoms of EMF Exposure

Exposure to EMF can cause a range of symptoms, including:






Skin rashes

Muscle and joint pain

Depression and anxiety

Concentration and memory problems


While these symptoms are not unique to EMF exposure and can have many other causes, it is important to be aware of them and seek medical attention if they persist.


Protection from EMF Exposure

There are several steps that individuals can take to protect themselves from EMF exposure in the workplace:

1. Conduct an EMF survey: An EMF survey is a professional assessment of the EMF levels in a workplace. This can help identify areas of high EMF exposure and allow for targeted solutions to reduce exposure.

2. Reduce exposure time: Minimising the amount of time spent in areas of high EMF exposure can reduce the overall exposure.

3. Increase distance from EMF sources: The strength of EMF decreases with distance, so increasing the distance between yourself and EMF sources can reduce exposure.

4. Shielding: Using shielding materials, such as curtains or films, can block EMF from entering your workspace.

5. Use wired connections: Using wired connections, such as ethernet cables, instead of wireless connections for electronic devices can significantly reduce exposure.

6. Use protective clothing: Protective clothing, such as aprons and gloves, can reduce exposure to EMF in the workplace.

7. Invest in low-emitting EMF devices: Investing in low-EMF electronic devices, such as monitors and printers, can also help reduce exposure in the workplace.


Employers also have a responsibility to protect their employees from the harmful effects of EMF exposure. This can include:

Providing information and training: Employers should provide information and training to employees about the sources of EMF in the workplace and how to reduce exposure.

Conducting an EMF survey: Employers should conduct an EMF survey to identify areas of high EMF exposure and implement targeted solutions to reduce exposure.

Implementing engineering controls: Employers can implement engineering controls, such as redesigning workspaces or installing shielding materials, to reduce EMF exposure.

Encouraging breaks: Employers should encourage employees to take breaks and move away from areas of high EMF exposure.

Providing protective equipment: Employers can provide protective equipment, such as aprons and gloves, to reduce exposure to EMF in the workplace.


In conclusion, EMF exposure is a real concern in the workplace. There are many sources of EMF, including electrical systems, electronic devices, and Wi-Fi routers, which can pose a danger to human health. Symptoms of EMF exposure can range from headaches and dizziness to depression and anxiety. It is important to take steps to protect yourself and your colleagues from the harmful effects of EMF exposure, including conducting an EMF survey, reducing exposure time, increasing distance from EMF sources, and using protective clothing and low-EMF devices. Employers also have a responsibility to protect their employees from the harmful effects of EMF exposure and should implement targeted solutions to reduce exposure in the workplace. Overall, being aware of the sources and dangers of EMF exposure can help create a safer and healthier workplace.

I had been in contact with EMF inspections LTd for the past few months while were were searching for a house to buy. They were incredibly professional and obliging and always happy to answer my questions. The survey itself was done in a very professional and friendly way. They have the option of next day booking. I received the report the following day, it was comprehensive and very informative and easy to understand. I would highly recommend their services to anyone. Thank you!
The survey was done quickly after the booking. The report was very clear to understand.

Thank you EMF Inspectrions Ltd for doing our Low Frequency EMF Survey. We had Galin who came to do the survey and he was brilliant. Not only was he polite but very informative and knew his stuff. We were in the process of purchasing a propery next to an electrical sub-station and was worried that the EMF could be penetrating the property. Galin went round the entire property inside and out, down the alley and in the garden and took readings. He explained the different levels of readings and reassured us that all of our readings were below the government guidelines. We are so pleased with the service. We booked on a Monday and had the survey on Wednesday (we could of had Tuesday if we wanted). The report was with us on Thursday which is brillianty written out to explain the readings for people who are not "experts". Would highly recommend using EMF Inspections Ltd to anyone. Thank you again!
