Because of the sheer number of study objects and methods, an evaluation of studies on induction of DNA damage by extremely low-frequency fields is difficult. In most studies, no genotoxic effects were found. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) concluded in its 2010 evaluation, that the studies on the effects of extremely low-frequency fields in cells do not show any induction of genotoxicity below 50 mT (ICNIRP (2010)).
