Abstract

Overview

In response to growing concerns over the health implications of radiofrequency from mobile phones, this study aims to provide essential scientific insights into the specific absorption rate (SAR) emitted by various GSM mobile phones in Ghana.

Methodology

• SAR levels were measured in approved and unapproved GSM mobile phones using a ComoSAR system.
• Measurements were conducted concerning international safety limits by ICNIRP and FCC.

Findings

• The study found that approved mobile phones had significantly higher SAR levels than unapproved phones.
• Highest SAR readings were consistently noted at the right ear position.
• The orientation of the phone, its regulatory status, and the frequency channel used during calls were significant determinants of the SAR values.

Conclusion

The study underscores the importance of regulatory approvals and correct usage practices in maintaining SAR within safe limits. It aligns with other studies but shows crucial disparities in SAR levels based on phone approval statuses and usage modalities, emphasizing the potential health risks associated with improper use or unregulated devices.
