Mutagenicity of complex exposure to static magnetic field (MF) and 50Hz MF was investigated. We developed a exposure system that can expose biological samples to complex magnetic field with up to 5T static MF and up to 1mT 50Hz MF simultaneously. To investigate the mutagenicity for this complex field, bacterial mutation assay (Ames test) using Salmonella typhimurium TA98 and TA100, and also yeast mutation assay using Saccharomyces cerevisiae XD83 were performed. It was found that gene conversion/recombination frequency in S. cerevisiae XD83 was slightly increased by exposure to complex MF with 5T static and 1mT, 50Hz MF while point mutation frequency in S. cerevisiae and S. typhimurium was not affected. Possible mechanism and evaluation of mutagenicity will be discussed. |
