There has been an immense amount of interest in the subject of EMF testing and mitigation. The main thrust of the study is to prove the adverse effects EMFs have on people and how they can be minimized. It has been proven over a long time that electromagnetic fields cause a variety of symptoms, some of which are pretty serious and can be life-threatening. It is known today that nearly every household has high levels of EMF present within it. The primary source of this is power lines and wireless phone technology.
The most dangerous aspect of electromagnetic radiation is that there is no way to avoid contact with it. It is emitted from sources, including electric power lines, cell phones, power plants, and even from medical equipment. It is necessary to minimize such exposure as much as possible. Electromagnetic fields can creep up on a person's cell phone, and they cannot turn it off. This could easily lead to brain cancer, migraines, and other such symptoms.
In addition, a person who works at a computer desk near a power plant will also be emitting electromagnetic radiation. The computer monitors work by emitting radio frequency into the air around them. This will then travel through the air and return with measurable strength to the monitor. When such high fields are combined with low-frequency waves from the sun or cell phones, it is more challenging to mitigate such exposure.
EMF testing and mitigation should include testing for other sources of EMF, such as radon gas that comes from groundwater. These naturally occur in moist climates and are mainly concentrated near mining areas. A home or building located near such radiation sources should have magnetic shielding applied to it. These not only reduce EMF levels but also block harmful radiation from penetrating the building or home.
Further testing should include measuring sources of electromagnetic fields emitted by various appliances. One of the most common is a microwave oven that is used in a home setting. Such a device emits microwaves with the strength of 10 gigahertz. Many of these frequencies go through unshielded walls or even concrete and will thus add to the overall EMR or EHF components in a room.
The results of testing done on the various types of electromagnetic fields should be recorded. This includes the strength of the electrical current, the power output, and any frequency levels associated with them. All of this information should be captured in a spreadsheet for further analysis. When necessary, an inspector should be called to talk to the person using the equipment and to gather additional information. The information collected can help with determining which devices or locations can be moved to minimize EMR exposure. It can also help in deciding how best to position items to keep them away from susceptible areas.
