  1. Health Hazards in Mobile and Computer Use Prof. Dr. S. Aswini Kumar. MD Professor of Medicine Govt. Medical College Hospital Thiruvananthapuram Email:


  3. Cell Phones

  4. 3,000,000,000 users world wide

  5. % of Population Using Mobiles

  6. India India is the 2nd largest market in the world for mobile phones. In India, mobile phones overtook fixed phones in 2005

  7. Situation in Kerala

  8. WHO Concern of Mobile Hazards Because of Electro -Magnetic Radiations

  9. Mobiles = Microwave Ovens

  10. Is it really dangerous?

  11. Thermal Effects Thermographic Change Heat generated on the face by 15 minutes of cell phone use due to their electromagnetic radiation

  12. Thermal Effect of Cell Phones

  13. Specific Absorption Rate Specific Absorption Rate (SAR) is a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field

  14. X-rays Background Roentgen (1895) X-Ray of his wife’s hand

  15. Radiation Dermatitis Radiologists began to suffer from radio dermatitis since 1896. But there was total denial of the existence of X-ray effects

  16. August 6, 1945, @ 8:15 A.M. local time  Hiroshima

  17. Electromagnetic Radiation

  18. 3 sources of radiation

  19. How is the radiation produced by a cell phone transmitted?

  20. Power Output of Mobile Phones CDMAMobile1 Watts GSM Mobile 2 Watts US Analog 3 Watts

  21. Power Output of Base stations Mobile phones

  22. ICNIRP Guideline

  23. ICNRP Reference Levels

  24. World Health Organization “Serious health effects like cancer are unlikely from mobile phones and their base stations” Based upon the consensus view of medical and scientific communities But ….

  25. Mobile phones open up the Blood Brain Barrier

  26. Children are more prone to radiation

  27. Pregnancy EMR may affect the fetus

  28. ? Can moblies cause brain tumors?

  29. Studies on Brain Cancer & Mobiles

  30. Theory behind brain tumors

  31. Risk of Acoustic Neuroma

  32. Salivary Gland Tumors An Israeli study showed that heavy mobile phone use can cause salivary gland tumors

  33. Radiation from cell phones can interact with electronic devices

  34. Mobile phones are banned in majority of air planes

  35. Mobile Phone & Defibrillators

  36. Cell phones may interfere with pacemakers

  37. Indirect Effects Driving, while using a mobile phone is dangerous

  38. Cell Phones Cause Traffic Accidents Risk of accidents ↑by 4 times

  39. Banning cell phones while driving New Delhi Only 4 states Mumbai Ineffective due to lack of visible enforcement Andhra Kerala

  40. Mobile cycling Mayor of London, Boris Johnson
