Intermediate frequency magnetic fields do not have mutagenic, co-mutagenic or gene conversion potentials in microbial genotoxicity tests

Evaluation of effects of intermediate frequency magnetic field on DNA methylation

“…However, in the point of view of carcinogenicity, a few studies have been reported. Lack of genotoxicity of IF-MFs (20 kHz, up to 1.1 mT for long term exposure [4], 23 kHz, 6.05 mT for short term exposure [5], lack of effect on micronucleus frequency) [6] and lack of effect on gene mutation [7] have already been reported. All of the data suggest that possibility of carcinogenicity by exposure to IF-MFs is extremely low.…”

Intermediate frequency magnetic fields generated by an induction heating (IH) cooktop do not affect genotoxicities and expression of heat shock proteins

“…However, very few in vitro effects have been studied. It has been reported that IF magnetic fields, i.e., at 2 kHz and 0.91 mT, 20 kHz and 1.1 mT, and 60 kHz and 0.11 mT, did not exhibit mutagenic, co-mutagenic effects or gene conversion in microbial genotoxicity (Nakasono et al 2008). We recently reported that a 23 kHz magnetic field at 532 mT, which is approximately 80 times higher than the reference level in the ICNIRP guidelines, did not cause genotoxicity in vitro (Miyakoshi et al 2007).…”

Expression of Heat Shock Proteins in Human Fibroblast Cells under Magnetic Resonant Coupling Wireless Power Transfer

“…Induction heating cookers and mobile phones, which are primary examples of EMF-related technology, have been studied extensively using both dosimetric and experimental methods to evaluate their potential health risks [6][7][8][9][10][11]. In contrast, the potential health risks of EMFs from WPT using the resonant coupling phenomenon have already been discussed based on the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines and dosimetric evaluation [12][13][14][15], but there have been very few experimental evaluations [16,17].…”
