Electromagnetic radiation generated by cell phone and the relationship with the human's health is not a new affair. From the time when the used of cellular phone (cell) had increased rapidly over the long-ago, people are becoming more concern with their health when dealing with the electromagnetic radiation. This type of radiation would leads to heating of body tissue at particular rate called the thermal radiation. Thermal radiation, it depends on the signal frequency of the energy, the power density of the radio frequency field that beats the body and the polarization of wave, the result of thermal distribution image generated by cell phone towards human head from thermal imaging camera. The investigation is conducted in a laboratory with average of 45 minutes talking hour with two different types of mobile phone having internal and external antenna.
