EM Watch from south England had a very interesting article on Computer radiation.
If you use computers at work or at home, or both, then computers could be your biggest source of Electromagnetic Radiation (EMR). Could this radiation threaten your health?
Computers today can generate up to four types of Electromagnetic Radiation:
1 Electric Radiation
2. Magnetic Radiation
3. WiFi / Wireless / RF Radiation
4. Dirty Electricity
All types of radiation are potentially harmful – even the World Health Organization now calls them possible carcinogens (i.e. they may cause cancer).
In fact, this radiation has been linked with many serious diseases:
• Heart Disease
• Hormone imbalances
• Damage to nerves, immune system and reproductive systems.
Symptoms of Electromagnetic Radiation (EMR) Exposure
Symptoms of frequent and prolonged Electromagnetic Radiation (EMR) exposure are often dismissed as being caused by stress, overwork, or just getting older. These include
• Sleep disturbances
• Concentration and memory disorders
• Skin prickling, itching, burning or flushing sensations on the face or elsewhere
• Uncomfortable, dry or swollen mucous membranes in the throat, ears or sinuses
• Muscle and joint pains
• Even some heart palpitations
Electromagnetic Hypersensitivity (EHS)
Noticing symptoms related to Electromagnetic Radiation (EMR) exposure can be a sign that a person is developing a condition known as Electromagnetic Hypersensitivity (EHS).
With EHS, when an afflicted person is exposed to certain types of Electromagnetic Radiation (EMR), they often experience symptoms — usually one or more of those in the list above.
This can be a real problem for these people because they may experience pain and discomfort at very much lower levels of radiation than those normally considered “safe.” In severe cases, they may have to avoid any and all Electromagnetic Radiation (EMR) – a serious handicap in today’s world.
EHS is quite common. At least 3% of the population may be affected, and that percentage is apparently increasing quite rapidly. It is generally thought to be caused by over-exposure to EMR,
1. either a massive single exposure, or
2. More often a cumulative exposure over a long period.
Computer usage is frequently implicated in this process, especially when WiFi / Wireless communications are used. Fortunately, computer users may be able to reduce their EMR exposure by following some simple, easy-to-do guidelines and suggestions:
10 things you can do NOW to minimize radiation in your home.
Even a TV show on the AMC Network – “Better Call Saul” – deals with a person with an extreme case of Electromagnetic Hypersensitivity. Even though the person has an extreme case of Electromagnetic Hypersensitivity, we are all affected in some way or another.
How to avoid Electromagnetic Radiation (EMR) exposure from computer usage
To minimize the amount of radiation you absorb and the risk to your health:
1. Don’t get too close to Electromagnetic Radiation sources.
2. Use as little as possible WiFi / Wireless / RF with your computer and network equipment.
All the advice in this article boils down to one or both of these two suggestions.
Electromagnetic Radiation (EMR) Basics
Many people feel so overwhelmed by this issue of Electromagnetic Radiation that they just give up on it. They think that it really is not possible to live in the modern world without being exposed to radiation from one source or another, all day long. But with a little knowledge, it is possible. Any source of EMR creates a field of energy around it, called the electromagnetic field, or EMF. This field is strongest right at the source and gets progressively weaker the further away you are from the source — like heat from a fire. WiFi / Wireless / RF radiation gets weaker very slowly (which is why it is used for communications) so the EMF extends for a greater distance. It is usually not practical just to get further away from WiFi / Wireless / RF radiation – EMR sources. That is why we recommend wired alternatives, not wireless.
One baby monitor I measured was still unsafe at 30 feet.

Electromagnetic Radiation (EMR) from your Computer Screen
There are several sources of Electromagnetic Radiation in a typical computer. Most of them are inside the computer, but the screen (monitor) also radiates this kind of energy. Modern flat computer screens (LCD or LED) generally produce far less EMR than the old-fashioned CRT’s (cathode ray tube) screens did, and also less than the older flat screens. But move even flat screens as far away as possible.
If you have an Electric radiation & Magnetic radiation meter you can determine your own safe viewing distances. I recommend the ME3030B for Electric Radiation and Magnetic Radiation.
Low-frequency EMR sources inside your computer
The Electromagnetic Radiation inside your computer is the WiFi, power supply, and the disc drive motors. The WiFi is being generated 24 hours a day – unless you turn it off and hard wire your desktop PC. The power supply generates constant EMR. The disc drive only generates EMR when it is busy reading or writing data, which is pretty much all the time if you are using your computer. Right at this source, the Electromagnetic Radiation might be very strong. So if a part of your body is near or in direct contact with the computer or your laptop, that part of your body could be exposed to a very high Radiation. When working with a desktop computer, keep the computer case on the floor, not on your desk. And position it as far away from you as the cables will stretch. Of course you can’t do that with a laptop.
