Electromagnetic Radiation from Cell Phones Used in Dhaka City
M. Quamruzzaman, Munima Haque, Shahina Haque, and Utpal Chandra Das
14.5 Conclusion
It was obtained from the cell phone data that in some instances the radiated power has gone over the edge value. In some of the cases, the threshold of both electric field and magnetic field was higher in appliances. Cell phone categories had different power density/magnetic field/electric field values and also their date of manufacturing was not the same raging from few months to few years.
The safe distance for use of cell phone is “1” or 2.54 cm. Users are advised to use a hand free device which places more space involving the phone and the head of the user. People should try to use their cell phones a bit far from their heads (ear) beyond the threshold values, it is preferable to use hand free device, decrease the duration of talking, as well as using a well coverage area by towers. Also, texting can be done wherever necessary instead of talking. If someone follow the 3D’s (Distance, Degree and Duration), he/she may be free from risk of the EMR from mobile/cell phone. It is expected that this survey would be beneficial as a precautionary health measure for people using cell phones in Dhaka city which may be applicable for other parts of Bangladesh.

14.5.1 Limitations
During data collection many users did not show interest, some could not give exact answer, device manufacturing date was not available, regarding symptoms most of the user could not say (point out) what was his or her real problem/sufferings. Due to shortage of time many users could not reply properly.
