Absorption of 5G radiation in brain tissue as a function of frequency, power and time

Abstract

Overview

The widespread deployment of 5G communications has raised significant concerns over the effects of new radiofrequency (RF) radiations on living organisms. This study specifically looks into the RF exposure and its absorption levels within brain tissues using developments in sensitive thermal assessment methods.

Key Findings

• Investigation conducted in bovine brain tissue and a brain-simulating gel across 4G and 5G relevant frequencies (1.9 GHz, 4 GHz, and 39 GHz).
• Documentation of how temperature rise (ΔT) correlates with the specific absorption rate (SAR) and incident power density, providing new highly accurate measurement assessments.
• Notable increases in RF heating noted with higher frequencies due to smaller RF source wavelengths and greater power density at consistent exposure durations.
• Advanced thermal and electromagnetic simulation techniques were employed to detail the behavior of RF in brain tissue models.

Conclusion

This novel thermal method significantly enhances the resolution and accuracy in measuring thermal effects of RF on brain tissues, indicating potential health implications particularly linked to increased tissue temperatures resulting from 5G frequencies. These findings support the necessity for further studies to explore sustained exposure and its physiological impacts.
