Mobile phones can cook your brain

  1. 1. Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.  - Thomas A. Edison   Chirag Chaudasi
  2. 2. Hoax or Fact...? Chirag Chaudasi
  3. 3. <ul><li>Over the course of the past decade, numerous electromagnetic field sources have become the focus of health concerns, to name a few… </li></ul><ul><li>Radars </li></ul><ul><li>Power lines </li></ul><ul><li>Security devices </li></ul><ul><li>Microwave ovens </li></ul><ul><li>Computer and TV screens </li></ul><ul><li>Mobile phones & their base stations </li></ul>Chirag Chaudasi
  4. 4. Mobile Radiation <ul><li>Mobile phones use Electromagnetic Radiation in the Microwave *  range, which some believe may be harmful to human health </li></ul><ul><li>* Microwave frequency ranges from 300 MHz to 300 GHz </li></ul>Chirag Chaudasi
  5. 5. The International EMF Project <ul><li>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 </li></ul>Chirag Chaudasi
  6. 6. They Concluded <ul><li>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 </li></ul><ul><li>* Frequency range from 0–300 GHz </li></ul>Chirag Chaudasi
  7. 7. Concern <ul><li>As of June 2009, there were more than 4.3 billion users worldwide </li></ul><ul><li>The Electromagnetic Radiation density is higher than ever and increasing </li></ul><ul><li>Source: Market data summary (Q2 2009)&quot;. GSM association. Retrieved 2010-01-30 </li></ul>Chirag Chaudasi
  8. 8. Effects (proposed/under research) <ul><li>Radiation absorption </li></ul><ul><ul><li>Part of the radio waves emitted by a mobile telephone handset are absorbed by the human head </li></ul></ul><ul><li>Thermal effects </li></ul><ul><li>One well-understood effect of </li></ul><ul><li>microwave radiation is dielectric </li></ul><ul><li>heating </li></ul><ul><li>Non-thermal effects </li></ul><ul><li>Production of heat shock proteins in order to defend the cell against metabolic cell stress caused by heat </li></ul>Chirag Chaudasi
  9. 9. Effects…(2) <ul><li>Blood-brain barrier effects </li></ul><ul><li>Study on effects of microwave radiation on the rat brain found a leakage of albumin into the brain via a permeated blood-brain barrier </li></ul><ul><li>Cancer </li></ul><ul><li>In 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 </li></ul><ul><li>Cognitive effects </li></ul><ul><li>In 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 </li></ul>Chirag Chaudasi
  10. 10. Effects…(3) <ul><li>Electromagnetic hypersensitivity </li></ul><ul><li>Burning & tingling sensations in the skin of the head </li></ul><ul><li>Fatigue, sleep disturbances & dizziness </li></ul><ul><li>Loss of mental attention & slow reaction times </li></ul><ul><li>Headaches & disturbances of the digestive system </li></ul><ul><li>Genotoxic effects </li></ul><ul><li>Changes in reproductive capacity </li></ul><ul><li>Sleep effects </li></ul><ul><li>Sleep quality ( measurement of broken sleep) </li></ul>Chirag Chaudasi
  11. 11. Factors Effecting The Exposure <ul><li>Transmit Power </li></ul><ul><ul><li>GSM handset – 2 watts </li></ul></ul><ul><ul><li>US analogue phone - 3.6 watts </li></ul></ul><ul><ul><li>CDMA-2000 & D-AMPS - below 1 watt </li></ul></ul><ul><li>Distance between the Source & subject </li></ul><ul><li>Duration of exposure </li></ul>Chirag Chaudasi
  12. 12. Precautionary Measures <ul><li>Use hands-free to decrease the radiation to the head. </li></ul><ul><li>Keep the mobile phone away from the body. </li></ul><ul><li>Do not use telephone in a car without an external antenna. </li></ul>Chirag Chaudasi
  13. 13. Conclusion <ul><li>Over exposure to sun can cause cancer </li></ul><ul><li>Exposure to high temperature can burn </li></ul><ul><li>Prolonged use of medicine can cause disease/side effects </li></ul><ul><li>Same goes with effects of Mobile Radiation </li></ul>Chirag Chaudasi
  14. 14. Verdict <ul><li>There is no proven research that can concretely attribute Electromagnetic radiation hazards to the use of Mobile phones </li></ul><ul><li>The precautionary measures can be adopted to keep a check on exposure levels </li></ul><ul><li>' Biological effect ' does not equal ‘ Health hazard ‘ * </li></ul><ul><li>* </li></ul>Chirag Chaudasi
