Nowadays, the number of usages in mobile communication is increasing due to the dependency of society to a new and advanced technology driven by wireless communication systems. Almost every people worldwide use mobile phone or smart phone including children. Due to the increased number of users using mobile phone, it may lead to the exposure of the thermal radiation of the mobile phone towards human health. The thermal effects are due to electromagnetic exposure from the smart phone. A human head has been exposed to electromagnetic radiation emitted by the different Global system for Mobile Communication (GSM). A human head, especially skin near ear-skull region is very thin compared to the other part of the human body. When using a smart phone in a long period of time, this region will absorb heat emission from the smart phone/mobile devices. This leads to increasing of temperature around the head and some research would show that this effect would cause severe headache/migrain. An experimental study was conducted by using a volunteer to examine the effect of EM radiation produced when calling and using the smart phone. In this project a smart phone that served GSM 1800MHz are used. The average time of calling and using smart phone is approximately 45 minutes and the data are measured by thermographic methods using FLIR ONE Camera. The result shows that, with a certain period of time, the temperature of the ear skull and human’s face region increase due to the absorption of thermal radiation. From the result, a device is develop to alert the user on the temperature increase when using the respective device.
