Electromagnetic Fields EMF such as those produced by power lines have become a growing source of concern to the general public. Many epidemiological studies have linked EMF to carcinogenesis implying an underlying genetic phenomenon mediated by EMF. EMF can be subdivided into either electric fields E-field or magnetic fields B-field. Our research used a reverse mutagenesis bacteriophage T4D model to quantitatively study the effects of E-fields on a molecular genetic level. Statistical analysis of the data indicated that there was no significant difference p 0.05 in the mutagenic rate of phages grown in the presence of AC E-fields compared to the controls except at a field-strength of 1053 VM pO.04. This result is not consistent with the other values tested and at this time we are at a loss to explain what appears to be a decrease in background spontaneous reversion rate in the phage T4 mutant.
