Assessment of the Effect of Mobile Phone Radiations Based on Selected Mobile Devices and Network Providers

This paper examines the radiofrequency (RF) radiation emitted by various mobile devices and network providers analyzing how device models, operational states, and proximity to network towers influence radiation exposure. With increasing mobile usage and concern about RF radiation health effect, this study aims to understand variations in radiation levels from different devices and network providers. Finding highlights significant difference in radiation based on device model, usage state (idle vs calling) and proximity to base stations. The diversity of electromagnetic radiation from various network service operators and mobile devices was measured using a Spectran HF-4040 analyzer. The spectrum analyzer has been used along with many mobile devices including the iPhone 7, Samsung A2, Tecno Poison 2 and Infinix Hot S. The Spectran HF4040 analyzer is used to measure the electromagnetic radiation emitted by various types of mobile devices using different SIM cards. Many calls were made from mobile devices without shielding materials to the four selected network operators (MTN, Glo, Airtel and 9mobile). The measurement was compared with the limit value. It was found that: (i) radiation levels from mobile devices were consistently high regardless of differences in network and phone type. As far as radiation levels are concerned (ii) Glo has the highest and Mtn has the lowest. Recommendations include using a cell phone with a low specific absorption rate (SAR), switching to headphones or speakers whenever possible, using a radiation blocker or a bag or special headphones that reduce SAR, and public education campaigns on safety precautions for telephone users to protect from the potentially harmful effects of radiation from mobile technologies.
