How safe are mobile phones?

Mobile telephone is an indivisible part of today's life. Every human carries it, big and little too.Mobile telephone has become a mainly means for communication and its use grows every day, but it's interesting is it safe for a human's health? Wireless telephones give signals through radio frequencies (RF), they are the same frequencies which are used by a simple AM/FM radios.It's a long time that scientists have investigated that high frequency waves, the same X-Rays, cause a cancer.But a few is known about that famous risk-factors that are caused by a low frequency waves, which are given by mobile telephones.
A problem locates in that, widely useiment of mobile phones practically began since XXI century and this time is stillnot enough to do some trustworthy pins.Has begun observations on humans,who use mobile phones,but date of using mobile phones hesitates from 3 to 7 years,which doesnot give to do pins.Beam of radiation exposure to form swelling however needs a minimum 10 years,therefore to show risk-factors this needs sufficiently long time.

Mobile phone sends signals through outward or inward antennas,towards to nearest station.The far a station locates,the stronger radiative waves apports from telephone, to establish a connection.Therefore scientists conclude,that under the influence of radiation will be a humans living in that regions,whence telephonic stations locate far.Plenty of scientists and medical experts gives us recommendations to take different measures to protect ourselves from eradiation.A mainly recommendation is that,we must use a mobile phone during inevitability and wu must carry a mobile phone maximally far from a human's head. United States government already demanded mobile phones' producers,to give a maximal information their users about each model telephones eradiation.
