You can measure EMFs with an EMF meter. This device can be used to measure both the strength and direction of an EMF. Before you go out and buy a meter make sure you know the type of EMF you want to measure.
Don’t make the same mistake I did, I went on Amazon and bought a review with high reviews only to find out that it didn’t measure radio frequencies.
EMFs Can Be Measured In Terms Of
- Frequency, which is the number of times per second that an electromagnetic wave oscillates.
- Amplitude, which is the maximum strength of an electromagnetic wave.
- Wavelength, which is the distance between two successive peaks of an electromagnetic wave.
- Polarization, which is the direction of the electric field vector in an electromagnetic wave.
- Phase, which is the position of an electromagnetic wave in its cycle.
- Time, which is the duration of an electromagnetic wave.
The strength of an EMF is measured in volts per meter (V/m). EMF exposure can come from both natural and man-made sources.
Some studies have linked EMF exposure to having harmful effects including headaches, fatigue, anxiety, and skin problems.
To measure EMFs you need an EMF meter. Depending on the meter you can measure magnetic fields, electric fields and radio frequencies.
Guidelines
There is currently no federal regulation of EMF exposure in the United States. Some states have enacted their own EMF regulations, typically limiting EMF exposure to 0.5 mG.
The World Health Organization has set a “guideline” level of EMF exposure at 1 mG. There many people who disagree with their guideline.
How To Use An EMF Meter
Here is a great video showing how to use a EMF meter. The one is the video is my favourite meter the Trifield TF2 and you can read my review of the Trifield TF2 here.
What Are EMFs?
EMFs are electromagnetic fields. They are created by the movement of electrically charged particles. EMFs are found in nature (e.g. the Earth’s magnetic field), but they can also be created by human-made sources, such as power lines, laptops, cell phones, and microwave ovens.
What Are The Different Types?
There are four types of EMFs:
1. Electric fields – These are created by electrically charged particles and are measured in volts per meter (V/m). They are present everywhere in our environment, even when there are no electrical devices present.
2. Magnetic fields – These are created by moving electrically charged particles and are measured in gauss or tesla (G or T).
How Do They Affect The Human Body?
EMFs are invisible and are present everywhere in our environment. They are a type of non-ionizing radiation.
Some people are more sensitive to the effects of exposure than others.
There are a ton of studies linking exposure to harmful effects while others insist there isn’t a connection.
What Are The Sources?
There are a variety of sources of EMFs, both natural and man-made. Here are just a few examples.
EMFs are electromagnetic fields. They are produced whenever electricity is flowing – for example, from power lines, electrical appliances, and cell phones. EMFs can also be produced by natural sources, such as the sun and lightning.
EMFs are also emitted by some medical devices, such as MRIs and X-ray machines.
The Best EMF Protection
The two best ways of protection are free and that is to limit how much you use your devices and distance yourself as far away from them as possible.
Remember an easy way to know what is giving off the highest levels of electromagnetic fields is buy investing in an EMF reader.
How Can EMF Exposure Be Avoided?
There are a few ways to avoid EMF exposure:
- Use an EMF protection device.
- Stay away from power lines and electrical appliances.
- Use a Faraday cage or bag.
- Limit your time on devices that emit EMF.
- Keep your distance from EMF sources.
- Use EMF-blocking fabric or paint.
- Unplug from the grid.
