Electromagnetic Radiation towards Adult Human Head from Handheld Mobile Phones

As the number of mobile phone usage increased exponentially nowadays, issues related to the electromagnetic radiation produce by mobile phone is becoming a big concern in the society. Mobile phoneproduced electromagnetic wave, and when placed near the ear skull, will produce electromagnetic radiation so called thermal effect. The transfer of electromagnetic field to the body producing thermal effect leads to heating of body tissue at specific rate. This effect is differ depending on the period of time the mobile phone being usedand type of mobile phone. This paper discussed on the result of thermal distribution generated by handheld mobile phone towards adult human head via collection of image from thermal imaging camera. The analysis is conducted in an anechoic chamber with average of 45 minutes talking hour with two different types of mobilephone, internal and external antenna serving different radio frequency range, 900 MHz and 1800 MHz. The results showed 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 heatcompared to mobile phone with internal antenna.
