    Effect of the low-frequency magnetic fields on the living organisms

  • Original language description

    The effect of low-frequency magnetic fields on the bacteria Escherichia coli K12 Row is studied. Magnetic field was generated by the cylindrical coil (Bm =< 10mT, duration of exposure t=6 min, f=50 Hz). We tried to estimate the threshold value of the magnetic induction causing statistically significant biological effect. This value is about 0.7 mT. The dependence of the number of colony forming units (CFU) on the frequency showed the decrease of viability for all used frequencies (5-20 000 Hz). We triedto combine effect of magnetic field and UV irradiation. The ultraviolet rays kills bacteria in short time damaging their DNA. We found that magnetic field effect and UV effect are cumulative and additive. The targets of UV rays and magnetic fields in biological objects are probably different, so we can assume that magnetic field probably does not affects DNA of bacteria.

    Působení nízkofrekvenčních magnetických polí na organismy

  • Czech description

    Studovali jsme efekty nízkofrekvenčních magnetických polí na bakterie Escherichia coli K12 Row. Pokoušeli jsme se najít prahovou magnetickou indukci, při které již dochází k statisticky signifikantním biologickým efektům. Tato hodnota je okolo 0,7 mT. Naměřili jsme též závislost počtu CFU na použitých frekvencích (5-20000 Hz). Také jsme se pokusili kombinovat působení UV záření s magnetickým polem. Zjistili jsme, že jejich efekt je kumulativní a aditivní.
