摘要

In this study, we investigated whether extremely low frequency magnetic fields (ELFMF) induce DNA damage or physiological abnormality in the bacterial cell using bacteriophage lambda. By exposure to magnetic fields for about 8 hours, the bacteriophages shifted to lytic growth 2 times as often as control. The mitomycin C, mutagenic reagent, was shifted the bacteriophages from lysogenic to lytic growth 46-times as of the control. These results suggested that ELF magnetic field (60 Hz, 45 mT) did not induce DNA damage in the bacterial cell as mitomycin C. But ELF magnetic (60 Hz, 45 mT) might induce physiological damage in the bacterial cells.
