Abstract:
Electromagnetic radiation may be either useful or harmful to the human body according
to the electromagnetic dose. For each wavelength there is a safe dose above it body will
suffer from harmful symptoms such as dizziness, unstable sleeping, sever headache,
inability of concentration, panic for no reason. Excessive dose may cause cancer.
Egyptian law for enviroment should contain this safe electromagnetic dose limit, such
as: it is safe to use mobile only 20 minutes per day, it is safe to be examined by X rays
only 25 times in your life, ... ... etc. But it is not safe to live under high or medium
tension overhead transmission lines or in front of radar or T.V or radio antenna.
Keeping in mind that god had created us with no electric or magnetic fields inside us but
if we are subjected to any electric or magnetic field, instantaneously a counter similar
field is created.
