Abstract

Abstract Review of Radiofrequency Electromagnetic Field Effects

Overview

This comprehensive review evaluates the threshold of radiofrequency electromagnetic field (RF EMF) effects on the human brain. It integrates findings from multiple neurophysiological and behavioral studies spanning from 2007 to 2021.

Findings

  • Analysis of non-thermal mechanisms shows that no definitive threshold for RF EMF effects can be determined.
  • Experimental data suggests a 76.7% detection rate of RF EMF effects in resting EEG studies, with significant changes noted at levels as low as 2.45 V/m (SAR=0.003 W/kg).
  • EEG changes typically precede behavioral alterations and exhibit similarities to depression, particularly among the youth, indicating a potential health risk that warrants further attention.

Conclusion

No principal threshold for RF EMF effects could be determined; however, the detected effects at lower exposures and their similarities to symptoms of depression, especially in younger demographics, underscore the potential health risks. Future research should focus on systematic studies across different RF EMF levels to better understand the relationship and develop protective measures.
