Abstract : Mobile phone technology has brought important benefits to individuals, businesses, and society. The widespread use of mobile phones has raised public and scientific interest regarding exposure to electromagnetic radiation and its possible biological effects Like most technologies, there are negative effects that can arise as a result of using radiofrequency (RF) radiation source from mobile phones. Health effects can arise as a result of exposure to this radiation. In this study, power density and electromagnetic fields from mobile phones were measured using a handheld electromagnetic field meter GQ EMF 390. Measurements were obtained from some sources of electromagnetic field (EMF) from mobile phone users on active calls. The power density and electromagnetic field values were used to obtain the specific absorption rate of radiation in tissue (SAR).. This study statistically examined relationships among measured magnetic field strength, electric field strength, power density, and Specific Absorption Rate (SAR) in selected mobile phones. Data from 50 mobile phone samples were analyzed using Statistical Package for the Social Sciences (SPSS). Descriptive statistics, Pearson correlation, and multiple regression analyses were performed. Results showed that electric field strength had a very strong positive correlation with SAR (r = 0.979, p < 0.001), while magnetic field strength showed a moderate positive correlation (r = 0.358, p = 0.011). Power density had no significant relationship with SAR (r = -0.028, p = 0.849). Multiple regression revealed that electric field strength was the only significant independent predictor of SAR (p < 0.001), and the model explained 95.8% of the variance in SAR (R² = 0.958). The study concludes that electric field strength is the most influential measurable radiation parameter associated with SAR among the sampled devices.
