Öz This work was carried out to examine the possible potential health risks that result from the use of some commonly available mobile phones in Nigeria. The mobile phones subjected to test were Tecno S1, Touching T1, Infinix hot 6 and Itel 1701. Their electric field strength, magnetic field strength and power density varied significantly per call engagement mode at various varied distances of measurement. Also, their computed head SAR values were observed to be below the limit set by the International Conference on Non-ionising Radiation Protection. From a potential health hazard point of view, Tecno S1 was found to be the safest for use.
