Electromagnetic Waves and their Effects
Due to the increasing electromagnetic pollution caused by
many factors such as TV and radio channels, mobile phones, studies about
protection from electromagnetic waves have gained considerable importance.
Equipments such as mobile phones, radars, radios and some
others radiate electromagnetic waves which may be harmful for both human health
and sensitive electronic devices. In general, electromagnetic shielding may be
defined as the process of restricting the effect of electromagnetic field
between two areas.
Electromagnetic waves are formed by the combination of both
electrical and magnetic waves and characterized by a frequency and a weave
length. Electromagnetic interference (EMI) is known to effect sensitive
electronic devices as well as the human health in a negative way. When a high
frequency electromagnetic wave enters a human body, it vibrates molecules to
give out heat. The network of veins within high risk organs such as the eyes
could be weakened because this heat can not be easily dissipated. Moreover, it
could increase the possibility of leukemia and other cancers.
Human nervous system can be considered as a huge electronic
system with around 25 billion cells. The effect of electromagnetic fields onto
the natural circulation of that system may be negative. Some problems in
nervous system and blood circulation might occur due to this negative effect.
The electromagnetic shielding effectiveness of materials is
essential especially in the applications where the protection of sensitive
electronic devices and human health is taken into the consideration.
Figure below illustrates the possible electromagnetic
radiation sources surrounding human beings in daily life.
