Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.

Over the course of the past decade, numerous electromagnetic field sources have become the focus of health concerns, to name a few…
Radars
Power lines
Security devices
Microwave ovens
Computer and TV screens
Mobile phones & their base stations

Mobile Radiation
Mobile phones use Electromagnetic Radiation in the Microwave* range, which some believe may be harmful to human health
* Microwave frequency ranges from 300 MHz to 300 GHz
Chirag Chaudasi 4
The International EMF Project In response to public concern, the World Health
Organization established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz
Chirag Chaudasi 5
They Concluded
Extensive research has been conducted into possible health effects of exposure to many parts of the frequency spectrum* and found that they do not produce any known adverse health effect
* Frequency range from 0–300 GHz

Concern As of June 2009, there were more than 4.3 billion
users worldwide
The Electromagnetic Radiation density is higher than ever and increasing

Effects (proposed/under research)
Radiation absorptionPart of the radio waves emitted by a mobile telephone handset are absorbed by the human head
Thermal effectsOne well-understood effect of microwave radiation is dielectric heating
Non-thermal effectsProduction of heat shock proteins in order to defend the cell against
metabolic cell stress caused by heat

Effects…(2)
Blood-brain barrier effectsStudy on effects of microwave radiation on the rat brain found a
leakage of albumin into the brain via a permeated blood-brain barrier
CancerIn 2006 a large Danish study about the connection between mobile
phone use and cancer incidence published which followed over 420,000 Danish citizens for 20 years and showed no increased risk of cancer
Cognitive effectsIn 2009 a study confirmed longer (slower) response times to a spatial
working memory task when exposed to a standard GSM cellular phone placed next to the head of male subjects

Effects…(3)
Electromagnetic hypersensitivity
o Burning & tingling sensations in the skin of the head
o Fatigue, sleep disturbances & dizziness
o Loss of mental attention & slow reaction times
o Headaches & disturbances of the digestive system
Genotoxic effectsChanges in reproductive capacity
Sleep effectsSleep quality ( measurement of broken sleep)

Factors Effecting The Exposure Transmit Power
o GSM handset – 2 watts
o US analogue phone - 3.6 watts
o CDMA-2000 & D-AMPS - below 1 watt
Distance between the Source & subject
Duration of exposure
Chirag Chaudasi 11
Precautionary Measures
Use hands-free to decrease the radiation to the head.
Keep the mobile phone away from the body.
Do not use telephone in a car without an external antenna.
Chirag Chaudasi 12
Conclusion
Over exposure to sun can cause cancer
Exposure to high temperature can burn
Prolonged use of medicine can cause disease/side effects
Same goes with effects of Mobile Radiation
Chirag Chaudasi 13
Verdict
There is no proven research that can concretely
attribute Electromagnetic radiation hazards to the
use of Mobile phones
The precautionary measures can be adopted to keep
a check on exposure levels
'Biological effect' does not equal ‘Health hazard‘*
