Abstract

Abstract Overview

The study critically examines the impact of non-standard mobile phone radiation on human health through increased specific absorption rate (SAR) and temperature in human head models. It highlights potentially serious physiological effects due to minor temperature elevations in sensitive areas such as the eyes, brain, and skin.

Methodology and Findings

  • Analyzed the SAR and temperature rise in three-dimensional head models under different usage scenarios: voice calling, video calling, and texting.
  • Explored variables such as age of user, radiation power, and distance between mobile and head.
  • Results indicate significant overheating and high SAR values in certain cases, especially in children, exceeding established ICNIRP limits.
  • Identifies children as highly vulnerable to radiation effects, being at significant risk of serious adverse health effects compared to adults.

Conclusion

The research underlines the dangers posed by high radiation levels from non-standard mobile devices, demonstrating a dire need for stringent safety measures and guidelines to mitigate risks, particularly affecting children. It emphasizes the importance of continual research into transient thermal analysis and dosimetry for comprehensive safety assessments.
