Abstract

Overview

The research investigates the Specific Absorption Rate (SAR) and the E-field strength generated by mobile phone radiation on a model simulating the head of an adult and a child. This absorption is crucial as mobile phones become ubiquitous and are used extensively across all age groups.

Methodology

Using ANSYS HFSS, the study models the human head and a mobile phone's antenna to assess RF exposure through a dipole antenna type. The head model comprises six layers: brain, CSF, dura, bone, fat, and skin, reflecting the distribution of SAR in various layers due to mobile phone exposure.

Findings

  • Child heads show higher SAR due to different anatomical structures like layer thickness and electrical properties compared to adults.
  • The study flags potentially hazardous EM absorption levels, particularly concerning for children's physical and mental health.
  • The results indicate regulatory standards concerning SAR limits might need re-evaluation to address safety comprehensively, especially for close-contact wireless devices.

Conclusion

Significant differences in SAR levels between adults and children suggest a need for revisiting safety standards. Additionally, high rates of brain cancer associated with high local SAR levels highlight the potential long-term risks of mobile phone use.
