1. Electromagnetic Pollution And Its Health
Effects On The Organism
The Great New Scourge Of The 21 St Century
Let’s Not Repeat The Mistakes Of Our Past

2. Outline of Presentation
• Electromagnetic Radiation: Intro
• Microwave Radiation Effects
• SAR Limits
• Radiation Pattern of Cell tower antenna
• Effects on Plants, Animals, Birds &
Humans
• Suggested Solutions
• Conclusion

3. The Actual Problem
certanily we can not today dispense
with mobile phones where they
have became part of our lives each
person now have mobile phone as
result it is quick way to connect
with other ,with this technological
development must not forget that
the most important factor ,it is
health
The uncontrolled and progressive
growth of modern communication
technologies associated with
increased industrialization, has
exploded into one of the biggest
crisis of pollution the world has
seen during the 20th and 21st
century.

4. Electromagnetic Radiations
EMR causes significant health hazards on human,
animals, birds, plants and environment.

5. Mobile phones & Towers Statistics in malaysia
Antennas on Cell Phone tower
transmit in the frequency range
of:
• 869 - 890 MHz (CDMA)
• 935 - 960 MHz (GSM900)
• 1805 – 1880 MHz (GSM1800)
• 2110 – 2170 MHz (3G)
• 2300 MHz (4G)

6. Microwave Radiation Effects
• Microwave radiation effects are
classified as:
•Thermal
•Non-thermal
• The current exposure safety standards
are mainly based on the thermal
effects, which are inadequate.
• Non-thermal effects are several times
more harmful than thermal effects.

7. Heating Concept in Microwave
4.2 KW (4200 W) of microwave power
raises temperature of 1 Litre of water
by 10°C in 1 second.
Cell Phone - Ear Warming?
• Have you ever noticed the warm
sensation in ear after using mobile
phone for a long time?
Warm sensation > pain > tinnitus
Tinnitus is Ringxiety- sensation of cell
phone ring

8. SAR Limit for Mobiles & Towers
SAR (Specific absorption rate)
- Rate at which radiation is
absorbed by human body,
measured in watts per kg (W/kg).
•Since 2012 DoT has revised the
SAR values in mobile phones
sold in India to 1.6 W/Kg
(Maximum)
•For mobile towers also in 2012
DoT revised the maximum SAR
value to be 1.05 W/sq.m (For 3G
at 2100 MHz)

9. Radiation Pattern of a Cell Tower Antenna
Propagation of "main beam“ from antenna mounted on
a tower or roof top
People living within 50 to 300 meter radius are in the high
radiation zone (dark blue) and are more prone to ill-
effects of electromagnetic radiation.

10. Effect on Environment: Plants,Birds & Animals
4 cell towers near
output of most of fruit bearing trees
drastically reduced to < 5% after 2.5
years of cell tower installation.
Have you ever seen any bird near cell
towers?
•May be not because birds have more
volume and less weight, so heating
effect is very fast. Also interferes with
navigation and reproduction.
•Sheep, dogs, cats, rabbits living near
base stations also gets affected.

11. Biological Effects on Human Body

12. Our bodies act as antennas that absorb the radiation and convert it into alternating
eddy currents
These generate alternating voltages across cell membranes which remove structurally
important calcium ions
