Abstract

SAR Estimations in a Child Due to RF Exposures from Laptops

Overview: This pivotal study evaluates the effects of Radiofrequency (RF) exposures on children in a classroom setting stemming from the use of multiple laptops. Increased use of electronic devices in educational environments necessitates a deeper understanding of associated electromagnetic field (EMF) exposures.

Methodology: The research simulates a realistic classroom environment filled with 7-year-old girls, each using a laptop. These laptops are identified as potent sources of electromagnetic radiation.

  • Measurements: Specific Absorption Rate (psSAR) is meticulously measured in various body parts— head, back, and hands.
  • Findings: Notable increases in psSAR, with values escalating up to 40 times depending on the number and proximity of laptops.

Conclusion: The study's outcomes urge the fashioning of safer classroom settings and guidelines that consider the amplified EMF exposure due to widespread laptop usage. This research also highlights the critical need for age-specific safety protocols in schools utilizing digital educational tools.
