Abstract

Overview

This study investigates the effects of intermittent extremely low frequency (ELF) magnetic fields (MF) on umbilical cord blood lymphocytes (UCBL). The research aims to understand how different amplitudes of ELF-MF influence cell viability and apoptosis.

Findings

• UCBLs were isolated from healthy newborns and exposed to ELF-MF with varying amplitudes ranging from 3 µT to 12 µT.
• Assessment methods included flow cytometry to determine cell viability stages and reactive oxygen species levels were measured at different hours of exposure.
• Significant changes were observed in cell viability at specific ELF-MF intensities, particularly at 6.5 µT and 12 µT, with noted effects at, but not limited to, p-values < 0.05 and p = 0.057 for 8.5 µT.

Conclusion

The results indicate a distinct amplitude window between 6 µT and 13 µT for ELF-MF effects on UCBLs. These findings suggest significant health implications for exposure to ELF-MF within these specific ranges and underscore the necessity for further research into amplitude and frequency modulation in ELF-MF exposure.
