Abstract

 The intensity of electromagnetic radiation around selected mobile phones is in a bid to confirm their adherence to the specified radiofrequency exposure limit on non-ionizing radiation. Measurements were taken with the use of Radiofrequency Meter (RF) TM-96, 9V DC and Spectrum Analyzer (NA-773, 144/430 MHz) at distances 5 cm, 10 cm, 15 cm, 20 cm, 25 cm and 30 cm from the mobile phone users. The level of radiations from the selected mobile phones ranges from 0.3119 to 0.5407 mW/cm2 during dialing. Out of the tested mobile phones, the radiation levels of Asus, Infinix 3 and Siccoo X100 phones which are 0.5407, 0.5009 and 0.4506 mW/cm2 respectively are above the International Commission on Non-ionizing Radiation Protection (ICNIRP) reference level which is 0.45 mW/cm2. Result from measurement showed that high radiation levels from a transmitting handset occur between seeking for connection and call establishment. It was also confirmed that the physical condition of mobile phones affects its radiation level.
