NEW BIOLOGICAL DETECTION SYSTEM FOR WEAK ELF MAGNETIC FIELDS AND TESTING OF THE PARAMETRIC RESONANCE MODEL (Lednev 1991)

Abstract

A new detection system for weak, extremely low frequency (ELF) magnetic fields based on bioluminescence of the autotrophic dinoflagellate Gonyaulax sp. is presented. Due to its sensitivity to external factors, this biological system has already been thoroughly investigated and used for various biological research. In our study, the system was first tested for its capacity to respond to weak ELF magnetic fields (50 Hz, 11.5 mT; 50 Hz, 1.2 mT). After its sensitivity was established, the system was used to test the parametric resonance model proposed by Lednev in 1991. Our results seem to be consistent with the model predictions, especially when monitoring real-time effects of the exposure.
