Health Concerns Around
Cell Phones
Part of the radio waves emitted by a mobile telephone
handset is absorbed by the human head.
The radio waves emitted by a GSM handset, (Global
System for Mobile Communications) can have a peak
power of 2 watts.
An analogue phone has a maximum transmit power of 3.6
watts.
Other digital mobile technologies, such as CDMA and
TDMA, use lower output power, typically below 1 watt.
The maximum power output from a mobile phone is
regulated by the mobile phone standard it is following
and by the regulatory agencies in each country.
Swedish researchers from the University Lund, Salford,
Brun, Perrson, Eberhardt and Malmgren, have studied
the effects of microwave radiation on the rat brain.
They found a leakage of albumin into brain via a
permeated blood-brain barrier.
The rate at which radiation is absorbed by the human
body is measured by the Specific Absorption Rate
(SAR), and its maximum levels for modern handsets have
been set by governmental regulating agencies in many
countries.
Some users of mobile handsets have reported feeling
several unspecific symptoms during and after its use;
ranging from burning and tingling sensations in the
skin of the head and extremities, fatigue, sleep
disturbances, dizziness, loss of mental attention,
reaction times and memory retentiveness, headaches,
malaise, tachycardia (heart palpitations), to
disturbances of the digestive system all of which can
be attributed to psychological stress.
Although research is still undergoing and it’s not
entirely clear what the affects of cell phone use will
have, people continue to use it on a grand scale. With
research they hope to conclude the affects cell phones
use has in the near future.
