What Are Electromagnetic Fields?
Electromagnetic pollution is everywhere, and the subject of electromagnetic fields associated with health is an ongoing concern. The natural current of the earth is DC, or direct current, from its magnetic field. AC, or alternating current, is man-made and consists of a lower electromagnetic frequency to generate electricity that can run a variety of electrical products. These include all electrical appliances and electronic communication systems or devices.
Increase of Electromagnetic Fields
For years the earth had existed without the introduction of artificially developed alternating current. This all changed during the modern technological era. With these currents now added to the ever increasing propagation of broadcast radio signals and other communications phenomena, EMF, or electromagnetic fields have increased even more.
Electromagnetic Radiation
Electromagnetic radiation is often referred to as an electromagnetic field whenever its within lower frequencies. EMF and EMR are generally used interchangeably, and many studies and reports have raised concerns regarding the potential biological effects resulting from constant human exposure to these fields.
Sources of Electromagnetic Pollution
Some of the immediate sources of electromagnetic emissions include a variety of household appliances and commonly used devices. Such items as hair dryers, television sets, clothes washers and dryers, blenders, vacuum cleaners, microwave ovens and refrigerators are a few of the many culprits. It’s widely believed that cellular and portable telephones also contribute significantly.
Electromagnetic Field Protection
Because of increased public awareness, many devices and products have been developed to protect against potential radiation and electromagnetic exposure. The electromagnetic shield industry is growing significantly, ranging from electromagnetic mats to other EMF protection solutions.
