Abstract
We previously reported frequency-dependent effects of electromagnetic radiation (EMR) at microwave and at radio frequencies when amplitude was modulated with 16 or 60 Hz extra-low frequencies (ELF). This study was conducted primarily to test effects of magnetic fields induced by ELF ranging from 10 to 72 Hz generating a calculated magnetic flux density of 138.48 nT/rms. Escherichia coli cells, strain JM108 containing a plasmid having a neuron-specific gene, was used. Results show the most significant alteration of enzyme activities at 55 Hz and marginally significant effects at 15 and 60 Hz in exposed cells compared to control cells. Several other ELF frequencies tested did not show any difference between control and exposed cells. It is concluded that effects of magnetic fields at ELF are not linearly dependent and are effective only at specific frequencies, which are separated by wide ranges of noneffective ELF frequencies.
