Abstract

Study Overview

The research investigated the potential genotoxic effects of intermediate-frequency magnetic fields (IF-MF), specifically within the 85 kHz band, as used in wireless power-transfer (WPT) systems for electric vehicles. The focus was on potential health implications these fields could have, which is critically important since the technology is rapidly expanding in usage.

Study Findings

• Key method: a high-intensity IF-MF mouse exposure system, achieving a whole-body electric field of 54.1 V/m on erythroid differentiation in mice over a 2-week period (1 hour/day).
• Comparative analysis was performed between IF-MF exposed and sham-exposed mice using the micronucleus (MN) test and the Pig-a mutation assay.
• Results indicated no significant differences in genotoxic effects such as MN or Pig-a mutations in mature erythrocytes and reticulocytes.

Conclusion

The study found no evidence of genotoxicity in mice from exposure to IF-MFs over 2 times the ICNIRP guideline for occupational exposure, highlighting the potential safety of this technology under the tested conditions. These insights contribute valuable knowledge towards the ongoing applications and safety assessments of WPT systems.

Important Consideration

While the study did not show harmful effects under the specific test conditions, it is crucial for ongoing monitoring and rigorous testing to continue, enhancing our understanding of the implications as the technology sees broader use.
