Empirical study on specific absorption rate of head tissues due to induced heating of 4G cell phone radiation

Abstract

Overview

Extended use of mobile phones emits electromagnetic radiation, which may cause biological damage at the macromolecular level within the human body.

Methodology

• An empirical analysis was conducted using a phantom simulating human head tissues—skin, skull, and brain—to study prolonged exposure to mobile phone radiation.
• Radiation exposure was tested over long durations (600 seconds and more), monitoring temperature variations at specific points using sensitive thermocouple probes.
• Specific Absorption Rates (SAR) for brain, eye, and skin tissues were calculated based on these temperature variations and other parameters.

Findings

• The average temperature increase in the brain was 0.10 ± 0.05 °C at a depth of 30 mm, with an estimated SAR of 0.66 ± 0.35 W/kg.
• Temperature rise in the eye socket was measured at 0.03 ± 0.02 °C with a SAR of 0.15 ± 0.08 W/kg.
• The skin's temperature increased on average by 0.14 ± 0.05 °C, recording a SAR of 0.66 ± 0.42 W/kg.

Conclusion

Although the measured SAR values lie within the internationally recommended safe limit of 2 W/kg, the cumulative effects of prolonged and widespread use of mobile phones pose potential health risks that require further investigation and attention.
