EMF Protection against Invisible Electrical and Magnetic Fields
Electromagnetic fields (EMFs) are comprised of electrically charged particles moving through space in the form of waves generated by objects such as a laptops, cellphones, radios, and televisions. These fields are a combination of electrical and magnetic fields. Both exist whenever electricity is present, but can also occur separately. Electric fields are present when an appliance or electrical device is plugged in or run on battery. A device does not need to be turned on to produce an electric field, as it is a stationary charge. Electrical fields derive from voltage in the wire and are measured in volts per meter. A strong voltage means a greater electrical field. This can change when certain obstructions, such as trees or fences, block the passage of electricity. Oppositely, a magnetic field is defined by moving charges and is formed when there is a current flowing through a device. Magnetic fields are measured in amperes per meter. Obstructions do not interfere with magnetic fields. Once an electrical device is turned on and there is an active current, the object becomes surrounded by electromagnetic fields. Within these invisible fields lies a form of energy, referred to as radiation. Because all electronics that transmit or receive a signal are surrounded by electromagnetic radiation, it is important to be aware of EMF protection as a safety precaution.
All active electronic devices are surrounded by EMFs. The strength of the field is determined by the frequency of the electromagnetic waves. Common devices, such as laptops, cellphones, radios and televisions are encircled by low frequency electromagnetic fields. This means the frequency of the radiation is low, but still present. Power lines and satellite towers are also considered to be among low sources of radiation. High frequency EMFs emit high levels of radiation and can be found in ultraviolet (UV) light, x-rays and gamma rays. Ultraviolet light occurs naturally in sunlight, but may also be man-made in the case of tanning beds. X-rays are another form of high radiation that is used by doctors for diagnostic purposes. Low frequency electromagnetic fields do pose harm to people, but higher frequency fields can be lethal. Becoming knowledgeable about forms of EMF protection may be necessary if exposed to strong radiation sources.
The electromagnetic field is strongest at its source, meaning the closer an individual is to the electrical device, the more exposure he or she will have to its subsequent radiation. It can be hard to measure the amount of radiation being emitted from any given source due to various factors, such as the power consumption in the neighborhood, use of electrical appliances, amount of current circulating in the ground wire of the electrical distribution panel, and distance to neighbor’s power system. For that reason, and EMF protection purposes, increasing the distance to and time spent around electromagnetic fields can minimize potential dangerous exposures of these varying frequencies, even those that are indistinct in their strength.
Another source of EMF protection is radiation shields, which work as a barrier against electromagnetic radiation. You can find out about who offers these products including a lot more information on EMFs and radiation online.
