Abstract

Abstract Summary

Overview

This study investigates the impact of various call factors on the Specific Absorption Rate (SAR) levels of GSM mobile phones in Ghana in light of rising health concerns related to radiofrequency radiation.

Findings

• Measurements were conducted using a ComoSAR system on both approved and unapproved mobile phones.
• The highest recorded 10 g SAR was 0.51 W/kg and 1 g SAR was 0.99 W/kg, which are 25% and 62% of the limits set by the International Commission on Non-Ionizing Radiation Protection and the Federal Communication Commission, respectively.
• Statistically significant higher SAR values were observed in approved phones compared to unapproved ones.
• The study noted that the SAR values were generally higher on the right ear compared to the left.

Conclusion

Both the regulatory status and the physical orientation of the phone significantly influence the SAR levels. These findings underline the importance of compliance with regulatory standards to ensure user safety regarding radiofrequency emissions from mobile phones.
