Electromagnetic Field Levels of Selected Mobile Phones and their Harm-causing Potential on the Users

The aim of this study was to investigate some commonly-used mobile phones for the electromagnetic field radiations emitted by them so as to determine their harm-causing potential on the user’s health. The mobile phones under consideration were Itel Model 1701, Tecno Model S1, and Infinix Model 6. An Electrosmogmeter was employed for measurement of phones’ electromagnetic parameters (electrical field strength, magnetic field strength, and power density) at various distances (0.05, 0.15, 0.25, 0.35, and 0.45 m). The Specific absorption rate (SAR) was computed from the relevant mean data obtained at 0.05 m and compared with some standard stipulations. It was found that each of the measured parameters varied significantly with the distance from the radiation source (mobile phone). The computed head SAR values (6.23 – 74.12) x 10-8 W/kg were below the limits set by the International Conference on Non-Ionising Radiation Protection and Federal Communications Commission. Findings generally revealed that though Tecno Model S1 could be the safest for use, prolonged exposure to the emissions from the phones might be harmful to health.
