Intermediate frequency magnetic fields did not have genotoxic and promotion potentials in in vitro tests

摘要

In recent years, the use of new electrical appliances, that use or emit intermediate frequency (IF; 300 Hz to 10 MHz) electromagnetic fields (EMFs), has been increasing. We have investigated genotoxic and promotion potentials of a vertical and sinusoidal IF MF of 0.91mT (rms) at 2 kHz, 1.1mT (rms) at 20 kHz and 0.11mT (rms) at 60 kHz. We used microbial mutagenicity tests, gene conversion tests, micronucleus tests or mouse lymphoma assay for genotoxicity, and Bhas 42 promotion tests for promotion. The results indicate that the IF MFs did not have genotoxic nor promotion potentials in the experimental conditions.
