The study of radiation effects of mobile phones

Communication referred as an information transmission from one place to another place. It plays an important role especially in this modern generation. According to the research, the usage of mobile communication such as mobile phones had increased rapidly. With that, peoples concern about the health issues arise from the wide usage of mobile phones which are associated with the Radio Frequency (RF) exposure from the mobile phones. This project investigates the radiation effects of mobile phones towards human health. The main aim of this project is to determine the Specific Absorption Rate (SAR) values via Finite-Difference Time-Domain (FDTD) simulation in order to indicate the effects of mobile phones towards human health. This project concentrates on the SAR value computation of Ig and 109 of brain tissue. Throughout this project, two types of mobile phones either with internal or external antenna is taking into consideration. The frequencies 900MHz and 1800MHz are covered for simulation. In addition, the mobile phones input power is standardized as 600mW. According to the results, the SAR values obtained for Ig and 109 of brain tissue do not exceed the limit of .... threshold exposure, 2~g' Therefore it can be deduced that the mobile phones exhibit no adverse health effects towards human health. However, there are several temporary adverse health effects such as dizziness, headaches and fatigue. As a conclusion, the radiations of the mobile phones do not produce adverse health effects towards human health. Nevertheless, further investigations are required in order to provide concrete evidences on mobile phones radiation effects towards human health
