RÉSUMÉ

During 2000 to 2005 there were performed systematic investigations of particularities of the influence of low-intensity electromagnetic field upon various biological objects (vegetable seeds and germs) both at direct radiation influence upon them and indirectly by means of interaction between the biological objects and the preliminarily radiated water and water-containing solutions. The exposure to radiation has been performed in the discrete bandwidths of the extremely high frequencies (EHF), the broadband noise signal overlapping the SHF and EHF bands (f=25.86 ... 37.50 GHz) as well as with the help of the fractal noise radiation within the broad band of frequencies from high frequencies (HF) to SHF. The possibility of the electromagnetic modification of functional indicators by means of direct and indirect radiation of the biological objects is demonstrated. General laws and differences in the efficiency of the said influence are revealed. The dependence of the biological response upon the frequency, the spectrum bandwidth, type of the signal modulation as well as upon the total power load is provided. The special attention has to be paid to the effects occurring at the indirect influence of the electromagnetic fields upon the biological objects.
