WHAT EFFECTS DO MOBILE PHONES HAVE ON PEOPLE’S HEALTH?
One and only onehigh power base station with which allusers communicate.
NormalTelephone
System
Wired connection
The core idea that led to today’s
system was the cellular concept.
The cellular concept: multiple
lower-power base stations that
service mobile users within their
coverage area and handoff users
to neighboring base stations as
users move.
THE CELLULAR CONCEPT

1. RADIATION EFFECT A part of the radio waves emitted by a mobile telephone handset are absorbed by the human head.
The best known measure is SAR (Specific Absorption Rate), which measures the RF power absorbed by
the human body.
Note:
Temperature rise is very minimal in the
first few minutes.
Then rises sharply at about 15 minutes
Continued a very gradual increase
thereafter
•A typical GSM digital cellular phone operating at a maximum average power
output of about 0.25 watts (W) might results in a SAR of about 0.5-1.5 W/kg
averaged over a gram of tissue.
•This is often associated with a very low rise in brain temperature (maximum 0.1º
C) (Anderson and Joyner 1995; Vaberg 1997; van Leeuwen et al. 1999).
•This temperature rise increases with the length of the call as shown in this graph.

3. BLOOD BRAIN BARRIER EFFECTS
* Mobile phones open up the Blood Brain Barrier
4. CANCER & BRAIN TUMOUR
• Some researchers have argued
that so-called "non-thermal effects"
could be reinterpreted as a normal
cellular response to an increase in
temperature.
• The German biophysicist Roland
Glaser, for example, has argued
that there are several thermo-
receptor molecules in cells, and
that they activate a cascade of
second and third messenger
systems, gene expression
mechanisms and production
of heat shock proteins in order to
defend the cell against
metabolic cell stress caused by
heat.
Cell phones may interfere with pacemakers
5. EFFECT ON HEART•Studies suggest, the strength of these fields will not
affect ordinary heart rhythm or function.
•Can present a danger to those with an implanted
pacemaker, internal defibrillator or similar device.
•Problems most likely to arise when pacemakers and
defibrillators are being programmed or reset by
medical staff.
•Recommended that keep
cell phones and media
players at least six inches
from the generator
(implanted device).
