Abstract

Overview

Exposure to non-ionizing electromagnetic fields (EMF) has been discussed as a potential factor leading to brain tumors, among other exogenous and endogenous risk factors. However, the influence of EMF on human health remains controversial due to the conflicting results found in previous studies.

Findings

  • More than 50 scientific articles were reviewed to provide comprehensive evidence on the potential health risks associated with non-ionizing radiation (NIR).
  • The study conducted testing with various frequencies, durations, and intensities on tumoral and non-tumoral cells.
  • It was specifically noted that the viability of glioblastoma cells was influenced by the frequency of exposure, pinpointing 30 Hz (or frequencies nearby) as a critical 'window frequency' that could determine cellular response in both tumoral and non-tumoral cells.

Conclusion

This study emphasizes the potential biological impacts of 30 Hz frequencies in the context of EMF exposure, suggesting significant effects on cellular mechanisms, particularly in cancer-related cell lines.
