Abstract

Overview

The aim of this study was to investigate the effects of various intensities of extremely low-frequency magnetic fields on rat brain cells, particularly focusing on apoptosis, neurodegeneration, and trace element alterations.

Material and Method

  • A total of 35 adult male Wistar rats were used in this experiment, divided into four main groups.
  • Groups were subjected to 0 mT (control), 1 mT, 1.5 mT, and 2 mT magnetic field exposures.
  • Exposures occurred for 4 hours per day, 5 days a week for 30 days using 50 Hz fields in Helmholtz coils.

Findings

Exposure to increasing levels of extremely low-frequency magnetic fields led to:

  • Raised levels of calcium in the brain.
  • Increased rates of apoptosis in neural tissues.

Conclusion

Exposure to extremely low-frequency magnetic fields has been conclusively shown to induce neurodegeneration and apoptosis, alongside altering crucial trace elements in brain tissue. These physiological changes have potential implications for causing biological damages such as cancer. It is crucial to limit exposure to these fields in daily living to safeguard public health.
