Effect of handphone to people society

1. WHAT EFFECTS DO MOBILE
PHONES HAVE ON PEOPLE’S
HEALTH?

2. FIRST MOBILE TELEPHONE SYSTEM
One and only one
high power base
station with which all
users communicate.
Normal
Telephone
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

3. 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

4. •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.
Note:
Temperature rise is very minimal in the
first few minutes.
Then rises sharply at about 15 minutes
Continued a very gradual increase
thereafter

5. 3. BLOOD BRAIN BARRIER
EFFECTS
* Mobile phones open up the Blood Brain Barrier

6. 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.

7. 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.
Cell phones may interfere with pacemakers
•Recommended that keep cell
phones and media players at
least six inches from the
generator (implanted device).
