Abstract-Electromagnetic radiation produce by mobile phone and the relationship with the human's health is not a new issue nowadays. Since the used of mobile phone had increased rapidly over the past few years, people are becoming more concern with their health when dealing with the so-called electromagnetic radiation. This type of radiation would leads to heating of body tissue at specific rate called the thermal radiation. Thermal radiation depends on the frequency of the energy, the power density of the radio frequency field that strikes the body and the polarization of wave. This paper will discuss on the result collected from the thermal radiation generated by handheld mobile phone with frequency of 900 MHz towards adult human head. The analysis is conducted in a laboratory with average of 45 minutes talking hour with two different types of mobile phone, internal and external antenna. The results show an increased of heat especially at the place near the ear skull after 45 minutes of operation. When comparing both different types of mobile phone, mobile phone with external antenna produce more heat compared to mobile phone with internal antenna.

Mobile phones produce radio frequency signal that is transferred as Electromagnetic radiation (EMR). EMR has the ability to penetrate through semi solid substances especially human body's tissues and caused dielectric heating. This effect can be classified as thermal and non thermal radiation. The skin near ear skull region is very thin compare to other part of human body. When using mobile phone for a longer period of time, this area absorbs EMR easily that can affects human immune systems. This effect resulted the increased of temperature near the ear skull region. Experimental study was conducted by using a volunteer to examine the effect of EMR produced by two different mobile phones with serving frequency of 900MHz and 1800MHz. This study was done in a laboratory for average of 45 minutes of talking time. Data is collected every 5 minutes using thermal imaging camera and thermal couples' probes. It is shown that temperature near the ear-skull region increased rapidly at the average of 2-4°C differences compare to before the used of mobile phone. When using adds in tools, the temperature rose more gradually and minimally. It is proven that the EMR would not cause any adverse effect towards human health such as cancer or tumor.
