Abstract

Overview

The increased usage of mobile phones and other wireless devices has raised concerns about the effects of electromagnetic (EM) fields, especially in young children. This study evaluates the specific absorption rate (SAR) in children's heads by developing age-specific anatomical realistic head models, accounting for age-dependent changes in tissue properties.

Findings

  • Development of realistic head models that reflect age-specific anatomical structures and tissue properties.
  • Assessment of SAR levels in various age groups, showcasing significantly higher absorption in younger children compared to adults.
  • Discovery that previous models underestimated SAR levels in children due to not accounting for age-dependent characteristics.

Conclusion

The study concludes that the SAR levels in brain tissues of young children are considerably higher than in adults, suggesting that a lower limit on radiated power might be necessary to ensure EMF safety for children.
