The Effect of Network Mode on Mobile Phone Radiation

Abstract

The ubiquitous nature of mobile phones in recent times has led to growing concerns over the health implications of radio frequency radiation exposure particularly cancer. It has been generally accepted that the specific absorption rate of a mobile device is indicative of the expected electromagnetic fields generated. Many researchers have proposed that other external factors affect these levels. This study investigates the effect of network mode (2G and 3G) on mobile phone electromagnetic fields (EMF). Measurements of EMF around a mobile phone operating in 2G and 3G mode were recorded using an RF EMF meter. After careful analysis, the results showed 2G mode had higher initial (on contact) but rapidly decreasing fields while 3G mode showed lower but slower decaying fields such that after 65cm, 3G EMF values were higher. It can be concluded that the network mode has an effect on radiation and distance of use is a determining factor in personal exposure levels. Therefore, it is recommended that mobile phone subscribers apply the specified minimum separation distance (usually between 0.5 and 2.5cm) while using their mobile devices.
