Electromagnetic Radiations
EMR causes significant health hazards on human,
animals, birds, plants and environment.
7.5
Lakhs
900+
Million
Mobile phones & Towers Statistics
in India
 Population: 1.25 Billion
 Mobile Subscribers: 96
Crores (Approx.)
 Mobile phone towers:
7.5 Lakhs
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.
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
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)
Cell Tower Transmit
Frequencies
 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)
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.
Effect on Environment: Plants
4 cell towers near Gurgaon-Delhi Toll
Naka
Output of most of fruit bearing trees
drastically reduced to < 5% after 2.5
years of cell tower installation.
Effect on Environment: Birds &
Animals
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.
 Dairy cows – Decreased milk
production, developmental problems
and decline in overall health.
 Sheep, dogs, cats, rabbits living near
base stations also gets affected.
Biological Effects on Human
Body
‘Are cell phones
injurious’

SUGGESTED
SOLUTIONS
We have to decide
Wealth vs Health
Conclusion
 Until now, man has been absorbing the harmful,
unseen EM radiations without even being
aware of it, but now, with rapid advent in
technology this RF Radiation pollution has
started having ill effects on human health and
health of animals.
 Hence, there is an urgent need to take
precautionary steps.
