Mobile Growth Mobile phones have been in use since the 1980s. However, Their popularity increased tremendously in the 1990s and continues to grow steadily.
Electromagnetic Hazards • The electromagnetic hazard can be divided into two parts: • Thermal health hazards • Non-thermal health hazards
Specific Absorption Rate (SAR) The rate at which radiation is absorbed by the human body is measured by the Specific Absorption Rate (SAR).
Specific Absorption Rate (SAR) List of top 10 lowest radiation mobile phones in the US - SAR List of top 10 highest radiation mobile phones in the US - SAR
Health Effects • Headache • Sleep disturbances • Sickness • Amnesia • Loss of mental attention • Fatigue • Dizziness
Health Effects • Heart palpitations • Disturbances of the digestive system • Malaise • Burning and tingling sensations in the skin of the head and extremities • increases the risk of ear tumors
Can mobile phones crash airplanes? • The mobile phones can interrupt the normal operation of cockpit instruments, especially Global Positioning Systems (GPS) receivers which uses for landing and takeoff. • They found that Samsung SPH-N300 mobile phone had caused their GPS to lose satellite lock.
Can mobile phones crash airplanes? • They examined 385 commercial aircraft accident from 1990 to 1999, if the mobile phones had contributed to any accident, it didn't effect more than 6.5% of these accidents. • The average number of reported interference events might be as high as 23 per year.
Can mobile phones crash airplanes? • Some airplanes have the solution for business travelers who want to stay connected and networked; they have seat-back phones which its antenna is outside the aircraft.
Lawsuits • In the USA, a small number of personal injury lawsuits have been filed by individuals against mobile phones manufacturers, such as Motorola, NEC, Siemens and Nokia, on the basis of allegations of causation of brain cancer and death. • So far, most of these lawsuits have been dismissed by the courts, on lack of scientific evidence of such a causal relationship, and this has been reducing the motivation of tort lawyers eager to mine a new vein of health injury lawsuits.
What can we do? • Save your lengthy phone conversations for a telephone (landline). • Change to a mobile phone that has its antenna outside the vehicle. • Use a headset and place the phone away from your body. • Find out how much SAR energy is emitted from the mobile phone.
Conclusion • There is no evidence that microwave exposure from mobile phones causes cancer. • There is inconclusive evidence that such exposure accelerates the growth of an already-existing cancer. • More research on this issue needs to be carried out.
