In vivo genotoxicity of high-intensity intermediate frequency magnetic fields in somatic cells and germ cells

Abstract

Overview

Intermediate frequency magnetic fields (IF-MFs), typically around 85 kHz, are crucial in wireless power transfer (WPT) systems. Despite their widespread applications, there's a noticeable gap in safety data concerning exposure to these fields, especially during accidental high-intensity exposure events.

Study Details

• The study utilized an enhanced exposure system allowing intermittent exposure of mice to high-intensity IF-MF (87 V/m, 3.8 times the occupational exposure limit according to ICNIRP guidelines) every 3 seconds, with temperature control built in.

Findings

Examinations of hematopoietic cells using the micronucleus (MN) test and Pig-a assay showed no significant genotoxic effects when comparing IF-MF-exposed groups to sham-exposed groups. Similarly, germ cell analysis using both MN test and gpt assay confirmed the absence of genetic or chromosomal abnormalities resulting from IF-MF exposure.

Conclusion

The findings suggest that the specific settings of IF-MF used in this study do not cause genotoxic harm to somatic and germ cells, bolstering the case for the safe deployment of WPT systems. This information is vital for providing an evidence-based approach towards ensuring the safety of organisms in environments with IF-MF exposure.
