Believe it or not, there are some considerable health risks one faces when dealing with the invisible electromagnetic fields all around us. Electronic devices like mobile phones and larger appliances like refrigerators and microwaves continuously emit invisible electromagnetic fields that cannot be seen with the naked eye, but that can be detected with a special device known as an electromagnetic field detector or sensor. How can these invisible waves of energy be harmful to humans? The question as to whether or not EMF waves are harmful or not remains a heavily debated subject and many people remain seriously concerned about the potential hazards associated with exposure to EMF waves.
Electromagnetic fields are naturally generated fields that emanate from objects which are electrically charged. Experts have studied how these invisible waves of energy effect animals and humans and various studies suggest a number of health risks associated with exposure to electromagnetic fields. In the early 1970s electromagnetic fields were linked to the onset of childhood leukemia, and other studies have revealed that electromagnetic fields can cause pacemakers to malfunction as well as other equipment and monitors. Electromagnetic energies have also been linked to other illnesses, cancers, and birth defects in animals, too.
Different appliances produce different amounts of electromagnetic energy. For instance, one's microwave emanates an electromagnetic field measured at 300 milliGuass when gauged from six feet away from the device. A hairdryer might generate 700 milliGuass. Even an electric blanket generates electromagnetic energy and exposes the sleeper to potentially hazardous energies. Many people have serious concerns over the use of computer technologies and mobile devices too since both of the latter emit electromagnetic fields of various levels and human beings are exposed to such devices all of the time.
To avoid potential dangers associated with electromagnetic exposure, it is recommended that individuals minimize their exposure to potential electromagnetic sources, if it is at all possible to do so. People are advised to distance themselves from known sources of electromagnetic energy. Sources can be identified with an inexpensive device known as an electromagnetic detector. A cell sensor device costs no more than 35 to 40 dollars and will give the user of the device a clear indication where EMF energies are emanating from in one's home, so that they can better distance themselves from such energies when possible. Some experts suggest the use of a Faraday cage to shield or shell any item that is capable of generating electromagnetic energies, but this is not always a practical application.
A Faraday cage is merely a metal cage that keeps all forms of electromagnetic energy out of the cage's interior. The latter types of cages are recommended for work environments where the risk of high exposure to electromagnetic fields is evident. The problem that arises when using faraday cages, however, is that the cage will not permit any EMF signals inside the cages interior and this can inhibit the ability of various electronics to work within the cage's structure.
